Formulación de una metodología teórico – práctica para el diseño de sistemas de control automático de bombas, mediante simulaciones en Matlab

Abstract

The present work describes the development of an automatic control system based on a domestic heating system, which consists of: recirculation pumps, control valves (actuators), temperature and flow (feedback) sensors, PID controllers and heat exchangers (plant). It is a non-linear system and to be able to represent this process, you have to linearize, model and get your transfer functions. For this analysis and its respective control in closed loop, will be used tools based on the simulation platform "Simulink" of Matlab. One of the facilities of this software is to perform simulations of automatic control systems using digital processing platforms, prior to a future implementation of the system, allowing to guarantee the reliability of the process. During the development of the system, graphs will be obtained of the output signals emitted by the pumps and radiators, in order to visualize the closed loop systems of the process. By using control techniques, you can see the effects of the system controllers, which are responsible for controlling the amount of water needed to the radiators and obtain a temperature that allows to operate safely. In addition, it can be used as a basis for future studies, in which it is desired to go deeper into this type of control systems.
