An anti-windup scheme with embedded internal model control anti-windup for improved performance

摘要

This paper considers the synthesis of an anti-windup(AW) compensator which comprises an internal model control(IMC) antiwindup compensator and a linear anti-windup compensator, for stable linear plants subject to input saturation. Built on the conventional internal model control antiwindup scheme which preserves the stability and stability robustness of the unconstrained linear closed-loop system, the proposed antiwindup scheme aims to improve the performance of the constrained closed-loop system by including another anti-windup compensator.
