Control Systems with Actuator Saturation: Anti-windup Mechanism and its Activation
Zongli Lin, Shanghai Jiaotong University
Abstract:
Every physical actuator is subject to saturation. It has been well recognized that, when the actuator saturates, the performance of the closed-loop system designed without considering actuator saturation may seriously deteriorate. In extreme cases, the system stability may even be lost. This talk will illustrate how actuator saturation adversely affects the behavior of a control system and explain how such adverse effects of actuator saturation can be mitigated by anti-windup mechanisms. In particular, our recent work on the design of an anticipatory anti-windup design is discussed.
