摘要

This paper focuses on the anti-windup-based dynamic controller synthesis problem for a certain class of nonlinear systems subject to actuator saturation. Based on the Linear-Fractional Representation (LFR) techniques, the original system is transformed into a linear system incorporating a sector-bounded nonlinearity and a saturation nonlinearity with an additional linear-fractional constraint. By using a quadratic Lyapunov function and with a modified sector condition describing the saturation nonlinearity, LMI-based conditions for the synthesis of an anti-windup-based dynamic controller are presented aiming at enlarging the estimated region of attraction (ROA) of the closed-loop systems. A numerical example illustrates the effectiveness of the proposed approaches.
