Desarrollo de un control de temperatura PI con integrador de clegg sintonizado por PSO

Abstract

The PI temperature control with clegg integrator is a reset-based control system, which consists of a PI (Proportional-Integral) linear controller with a built-in reset or zero reset mechanism, known as the clegg integrator(CI). The reset of the controller is generated only when a condition is met. The condition that triggers the reset in this case is when the sensor temperature reaches the desired value or reference value. It can also be said that the reset is activated when the error between the output and the input is zero. The tuning values of the linear PI control are obtained by using the PSO particle swarm optimization. The basis of PSO is simply to make a population of tuning values converge towards the best possible solution for linear PI control. The purpose of this paper is to implement a practical reset-based temperature control system and to tune it using the PSO algorithm. Then we evaluate the performance of the implemented controller based on resetting, against a PI control that is the most used classic alternative. Finally, the results show the properties of reset-based systems versus the classical alternative in a real physical plant.
