Nonlinear dynamic regional anti-windup compensator (RAWC) schema for constrained nonlinear systems

This paper concentrate on the study of the synthesis of regional anti-windup compensator (RAWC) for saturated nonlinear control system, by using quadratic Lyapunov functional, an estimate region of convergence, regional modified sector condition and Lipschitz condition. Further L

gain minimization is employed to minimize L

gain of the decoupled nonlinear component. Based on linear matrix inequality (LMI) condition, it is revealed that for stable and unstable nonlinear system, the RAWC can accomplish exponential and L

exponential stability. Two numerical examples are used to demonstrate the effectiveness of the suggested anti-windup methodology.
