Abstract

In the present work, the design, simulation and implementation of PID controllers and controllers in State Space are carried out for the QNET DC Motor Control Trainer didactic plant where both position and speed are controlled. The data acquisition is done through the NI ELVIS II card and provides position and current measurements, the speed and armature voltage variables are calculated mathematically for later use in the State Space controller. The control scheme in State Space consists of the feedback of the states and an integral part that allows the rejection before disturbances, for the PID control scheme in the speed variable there is a PI controller and for the position variable a controller is used. P.S. For the controller performance test, the Matlab/Simulink software is used with the mathematical model of the system and later tests are carried out with the physical system using the LabVIEW software. The controllers designed were subjected to changes of reference and tests against disturbances not modeled in the control signal and output of the system, to observe the behavior that each of the controllers presents before each of the mentioned tests. From the tests carried out, the performance indices ISE, ISU and establishment time were obtained for both physical tests and at the simulation level to carry out a comparative analysis between the controllers designed depending on the variable to be controlled. Finally, there is the design of the interfaces in both AppDesigner and LabVIEW which allow the manipulation and change of the constants of all the controllers designed for the QNET DC Motor Control Trainer teaching plant.
