DESIGN OF PD-TYPE ANTI-WINDUP COMPENSATORS FOR CONTROL SYSTEMS WITH INPUT AND OUTPUT SATURATION NONLINEARITIES VIA LINEAR MATRIX INEQUALITY

摘要

This paper presents a methodology for the design of proportional-derivative-type anti-windup compensators (PDAWCs) for linear time-invariant systems with input and output saturation nonlinearities. A linear matrix inequality (LMI) condition for a closed-loop control system representation is given to take into account the nonlinearities and disturbance. A PDAWC is designed by solving the LMI problem. A numerical example is shown to confirm the effectiveness of the proposed design method.
