Anti-windup design for internal model control based on the optimal compensator

This paper addresses an anti-windup analytical design method based on the optimal compensator, by adding a parameter α to the sub-controllers to optimize the compensator with a design procedure formulated as a constrained optimization problem, which depend on new particle swarm optimization (NPSO) algorithm, applicable to SISO and MIMO systems with time delay/coupling plants. The proposed anti-windup design provides the minimum integral of squared error (ISE). Illustrative examples are given to show the effectiveness and merits of the Anti-windup IMC design based on the optimal compensator.
