Abstract :
This paper presents a coordination strategy of anti-windup mechanisms based on conditioning by ¿input scaling¿. It is specially designed to be used in distributed control systems with PID controllers. The study considers three cases of TITO control systems: decentralized control, centralized control with decoupler and centralized control with four PID. In them, the allowable region in the control signal space is transformed into an allowable region in the signal space of PID controllers. In this way, PID controllers are able to keep their integral term at a proper value when actuator saturates. The coordination strategy assures that the control signals are always inside these allowable control regions. The proposed methodology is applied to two representative processes.
