Diseño y simulación de algoritmos anti-windup para control modo deslizante aplicados a sistemas aproximables a un sistema de primer orden con retardo

Abstract

The advance of the industry has generated the development of control systems with greater robustness. In this way born the sliding mode controller; where one of the main characteristics of this innovative control strategy is its robustness against uncertainty in modeling and perturbations. However, having an integral term within the controller can present a very studied problem in PID controllers known as Windup effect. The problem caused by the Windup effect is related to the transitory response generating oscillations, slow responses and in many cases making the system unstable. The objective of this work was to develop Anti-Windup algorithms that work within the sliding surface of the sliding mode controller in order to improve the transient response of the system and improve its evaluated performance through performance indexes such as ISE and ITSE. The algorithms were tested in two non-linear systems and a linear system where they were subjected to different monitoring and regulation tests.
