One of the everyday problems in industrial process control is tuning PID controllers, so that in many cases, the empirical knowledge of the most experienced operators or classical methods as Ziegler Nichols one, which is used widely for its simplicity and popularity. However, in spite of the used values in the processes are useful, they are not the best, so we need new methods in order to optimize these values, so that, no energy is wasted on plants and it is possible to increase the life of the equipment. This paper presents a Tunable Auto PID Controller with a standard topology, which has a pre tuning method based on relay with an optimal adjustment of their profits using an algorithm based on swarm intelligence. This method is the Optimization by Particle Swarm – PSO, which was proposed by Kennedy and Eberhart in 1995, and inspired by the schools of fish and flocks of birds. The performance of the controller designed is compared with other two controllers tuned by the methods of Ziegler - Nichols and Genetic Algorithms – AG, by using the integral of absolute error – IAE of the response of the systems belonging to the processes studied in the CERFIN - SECAP.

This paper presents the application of computer vision algorithms to control two robotic agents in order to achieve a cooperative operation by moving an object into a semi-structured space from a starting point to a point of arrival. The system works based on an overhead camera, which captures the image and it is transmitted to a personal computer with Matlab R2013a, where the information is processed and the control actions are determined, which are transmitted to each agent wirelessly in order to perform these movements. The first movement is positioning in front of the object, the second one is the elevation of the object for later, through a coordinated movement, take it to the destination point.

The present work undertakes the development and implementation of a system to visualize the human biomechanical gait of the knee in the sagittal zone by means of sensors to visualize the affectation of the gonarthosis in the gait. Two inertial sensors were used to acquire signals corresponding to the angle generated between the leg and the thigh which were processed in a development board - Arduino one. Kalman and the complementary have been applied for the filter of the accelerometer and gyroscope signal. The next stage of digital processing was done at the software level with Matlab, once the signal was obtained wirelessly; Initially it is classified and normalized the human march, in addition, adjustments of curves are realized through a polinomio of seventh order of the marches acquired and selected and obtain the knee kinematics. We analyzed people without affectation, to store in the database and to visualize the affectation of the gait with people suffering from gonarthrosis through a graphical interface that allows the specialist to visualize the affectation in the gait.

Vision is in many respects the most complex sense of human physiology, overcome in complexity only by organs such as the brain. The Artificial Vision has developed a series of tools, to emulate the functioning of the view, solutions and practical application alternatives.
One of these options has been implemented to determine fatigue or tiredness in people, for vehicle assistance systems, supervision modules in nuclear power plants, etc. In this work, the design of a low cost system is developed using a Raspberry PI 3 card, where an algorithm designed in Open CV is housed. This system determines the fatigue using the PERCLOS index. The system can be used indistinctly, both at night with light in the near infrared spectrum and also in the day without additional light. The operation of the system was verified in two light moving vehicles and in a concierge cabin both day and night.

In this work a method of tuning a model predictive controller (MPC) through an extended Kalman filter is presented. The system on which the algorithm is tested is a continuous stirred tank reactor known as CSTR. The development of the work begins with the mathematical model of the CSTR through a process of identification of a linear system of reduced order. Subsequently, the predictive controller is formulated from a state space system. Finally, the extended Kalman filter algorithm is implemented to tune the error weights and control effort from the MPC.

Distributed Generation (DG) based on solar photovoltaic- and wind energy-farms conversion systems has become a trend on many countries in order to reduce the carbon emissions, preserve the environment and mitigate the global warming. Nevertheless, DG presents output power fluctuations as they depend on environment conditions. Thus, this study focus on overcoming the inherent drawbacks of DG by means of the design and simulation of a Virtual Power Plant (VPP) that integrates in a controlled way different distributed generators, energy storage systems, power converters and loads. Mathematical models, maximum power point algorithms, nested and single loop control schemes, classic, sliding and vector control strategies, network synchronization and integration mechanism, among others, are widely explained themes during the development of this study. Finally, a Sliding-Mode Control in a cascade scheme is proposed in order to attain a suitable energy use of the system with a fast and robust dynamic response to changes of reference and perturbations.

This work is done on a rotational inverted pendulum that is an unstable system of highly non-linear dynamics; in such a way that to act on this system it is necessary to design controllers that can react adequately to external disturbances and modeling uncertainties. In this context, the objective of this work is to look for a control strategy that combines some of the best characteristics of existing techniques, so a control is proposed that combines the optimality of the LQR and the robustness of the VSC based on both the model linear as in the fuzzy TS model, the designed controllers are applied to the rotational inverted pendulum, in order to obtain a better response in both steady state and transient, less susceptible to external disturbances and modeling uncertainties in both simulation and real ROTPEN system.

Hexarotors are UAVs (Unmanned aerial vehicles) within the type of multirotor, their main characteristics are: their takeoff and landing are performed vertically, they have the ability to stay suspended in one position, aircrafts capable of maintaining a controlled flight in an autonomous way. The DJI F550 hexarotor uses an Arduino DUE embedded card as electronic control or drone brain. The card is connected to an inertial measurement unit (IMU), whose measurements are passed through a smoothing Kalman filter. The filtered data is processed at the embedded card to estimate the orientation angles and then the SMC control for the orientation angles (roll, pitch and yaw angles) is performed. For the movement of the hexarotor a hand control is used, which allows to vary the height and the angles of orientation of the hexarotor in order to control its displacement. In the hexarotor two types of controllers were implemented, the SMC and the PID controlers for the angles of orientation. The operation of these controllers in similar conditions is compared and then using the quadratic error integral method the best controller is shown.

Companies that develop programming software for supervisory control and data acquisition systems worldwide offer high-cost applications. Each company that sells the software has its own version of the HMI developer and the connection software between it and the industrial network, generating a price for each system. Ecuadorian's industrial sector when buying machinery, obeys a logic of cost-benefit, regardless controller brand, leaving relegated the acquisition of a supervisory control system to be an extra cost service and does not affect machine operation, but losing the great benefits of production data or critical parameters in real time.
With this background, a computational tool has been developed to reduce the purchase of foreign software, with the implementation of free tools and easy application configuration, developing according international technical specifications the "de facto" protocol of the industry called MODBUS. Access to the display of the supervisory control system and data acquisition is done through the Internet using any browser, which makes its access easy for end user.

This development presents a software application that can be used by oil companies in their operations, for the analysis of oil wells startup scenarios when an electrical restriction is present in the electrical power interconnected system. The developed software has a data acquisition module based on the Client-Server architecture and using the OPC standard. This allows the electrical data collection from a data monitoring, control and acquisition system SCADA and the petroleum data collection from a well monitoring system. The acquired electrical and oil data is used by two algorithms. The first, based on graphs theory and implemented in C# language is used for electrical islands identification and for computing the available power reserve. The second, based on a genetic algorithm, is implemented in C ++ programming language and it is used for finding the best scenarios of oil wells startup. For the visualization of the results a user interface has been developed under the Windows platform. This software application has been tested in a simulation environment.

The present thesis uses the method of finite element analysis to create and simulate the behavior of a permanent magnet synchronous motor (PMSM), power circuit and V / F scalar controller using Ansys Electronics Desktop and Matlab softwares. The power circuit is designed and simulated using Ansys Simplorer and the V / F scalar controller using Matlab to work as a co-simulation. The co-simulation model created allows obtaining results that are much closer to the real behavior of the mechanical and electrical components since it uses modeling using the finite element technique. The scalar control created in Matlab will allow to verify the behavior in the motor speed and torque control to verify the results. The results obtained from the simulations of the models of the PMSM created with Ansys Electronics Desktop and Matlab will be compared and analyzed to validate the present work.

In this project a formation control algorithm is developed for the trajectory tracking of a quadcopter’s formation, this control system is designed based on the model of the quadcopters involved in the formation. The control systems developed for the trajectory tracking of the quadcopters in formation are a PID-like controller and a Sliding Mode Controller algorithm. Additionally, the trajectory tracking of a single quadcopter is performed through a PID controller and a SMC controller for the altitude, attitude and position. Accordingly, with the nature of the system, the uncertainty, no-linearity and time variations presented in the models, the applied control systems must be robust enough to overcome the disturbances and uncertainties, and allowing the quadcopters to fulfil certain tasks and remain the system stable. One control objective of the formation control is achieving tasks that in groups are easily to complete rather than with a single agent, allowing performing a variety of assignments and optimizing the consumption of energy. Therefore, the quad copter’s formations allow applications as a surveillance from multiple points of view and exploration of large areas, transport of large objects and even carry out rescue actions that involve a lot of risk. All the facts mentioned motivates the development of the present work.

The present degree work is focused on the design and implementation of a predictive controller based on the model by its acronym in English MPC, and a control by sliding modes (SMC), applied to the rotation and elevation of the laboratory equipment Twin Rotor System MIMO (TRMS) that simulates the behavior of a helicopter.
To comply with the objective of controlling the rotation and elevation of the TRMS system, we start with the study of the operation of the equipment, to obtain a linear model of the dynamics of the system, additionally we introduce control concepts that intervene in the design of the MPC and SMC controllers.
The controllers designed for the control of rotation and elevation are applied to the simulation and the real TRMS system, through a graphical interface designed in the Matlab software, which allows the user to manipulate the references, apply perturbations to the process, choose the controllers, visualize the system response and control signal, a window with the performance indices of the integral of the absolute error (IAE), integral of the quadratic error (ISE), is also included in the graphical interface, with which a comparison of the performance is made of the designed drivers.

In the present project has been made the fault detection in the insulators of the electric transmission line in block 46 (Mauro Dávalos Cordero "MDC") and block 47 (Paraíso-Biguno-Huachito-Intracampos "PBHI"), using artificial vision algorithms.
In the first instance the feature extractor SURF (Speeded-Up Robust Features) has been selected because it is a good descriptor for the detection of objects in conjunction with the Adaboost classifier ("Adaptive Boosting") to detect the isolator in the scene and then classify it as good or bad.
Secondly, photographs of another electric transmission line have been taken which form the Database "samples" with 200 images, of which 70% is used for the training of the classification methods and 30% for test and thus be able to locate faults in insulators such as breakage, fissure and dirt. The classification accuracy of each algorithm is detailed below: Adaboost (62.31%), Bayesian (75%), SVM (78.13%) and Neural Networks (81.25%).

This work makes the design and simulation of the contribution of three natural source generation systems: photovoltaic systems, wind system and hydroelectric system, controlled by search algorithms of maximum power of Incremental Conductance for being more efficient and more used in source systems renewable, and PI controllers that act on static power converters to later deliver this power to a common direct current bus. For the reserve of energy there is an energy storage system with Lithium-Ion batteries for storage over long periods. For the power output in the first instance, a multilevel inverter in controlled AC / DC bridge is used, with output filters and a transformer coupling with a network that can supply of energy for a variable load. The output of the system maintains a robust and rapid response to sudden changes in the input signals, these inputs have been taken from measurements made by MEER and CONELEC, with average values measured in Ecuador as they are; the wind in the central zone of the country, the lower solar radiation, and a hydroelectric system such as the Mini Central Gualaceo, all these signals measured in a daily period.

The prototype ball & plate is a highly unstable test plant and is a support for the teaching and implementation of various control techniques, in this proposal three algorithms are implemented and compared: SMC, FUZZY and FSMC. In this project, five wire resistive touch panel acts as the plate of the mechanism that permanently senses the position of the free ball, and as final control elements, two servomotors that allow manipulation of the inclination of the plate. For the acquisition and management of the plant's own signals, the Arduino Mega embedded card is used, communicated by serial link to interact continuously with the interface on the computer, through the MatLab / Simulink environment where the input data is processed, the controller works and the control signals are generated for each servomotor.

This work presents the design and comparison by simulation of PI and SMC controllers applied to a three-phase inverter connected to the grid. It starts from the DC/AC concepts and its main components such as: inverter, modulation techniques, synchronization techniques with the grid, filters and finally the study of control techniques.
In the design phase, a three-phase inverter with SPWM modulation is modeled, it continues with the design of an optimal LCL filter, then, the design of the synchronization technique with the grid SRF-PLL, concluding with the design of the PI and SMC controllers.
Each one of the system components are implemented in Simulink from Matlab and the designs are validated. Next, tests of the operation of the controllers are carried out through the simulation of injection of active and reactive power to the grid, as well as of real disturbances that exist in the grid (voltage dips), always verifying through THD measurements that the injected current corresponds to the limits imposed by IEEE519 standard for harmonic current limits. Finally, an analysis of the performance of the controllers is carried out, through the comparison of various parameters

The transmission and distribution of energy are areas of vital importance for the electrical power system that require high levels of reliability, so a failure in the system becomes a significant problem; for this reason, in recent years, methods based on artificial intelligence techniques, neural networks and others, have been proposed for analysis and solution papers of these. In this paper, a method for the classification of faults in Electrical Power Systems using Deep Learning implemented in an application created through App Designer is proposed. The classification of faults in transmission lines and the determination of the type of fault uses a method of feature vectors and categories using LSTM neural networks, in addition, the classification of the most common types of faults allows decisions to be made to reduce as much as possible the faults in the lines. The measurements that form the data used to train the LSTM neural network were obtained in DigSilent; furthermore, the creation, training and use of multi-layer Long-Short-Term-Memory (LSTM) networks was implemented in Matlab R2021a. The strong learning capability of LSTM networks is suitable for many time series in power transmission and distribution. The results obtained are promising for fault classification in power systems.

The present degree work describes the use of the Orocos middleware in the implementation of a PID position controller for a delta type parallel robot simulated in VREP using a reduced plate embedded system. For it, first an embedded development card was selected that meets the hardware requirements and suitable to run the UBUNTU MATE operating system, in which the OROCOS TOOLCHAIN package was installed and executed, this allowed the creation of components and execution of algorithms. Subsequently, the controller was designed based on the dynamic model of the parallel robot, considering the operating conditions and the control strategy to be applied. Next, the parallel robot scene was implemented in the VREP simulator, which is governed by the controller developed in the PYTHON programming language together with the OROCOS package that will allow its execution. Finally, the connection between the embedded card and the simulator was established in the personal computer where the simulated environment in VREP of the parallel robot is located, to verify the operation of the system.
