A Parameter-Dependent Anti-windup Compensation Design for LPV systems Subject to Actuator Saturation

Different from the conventional constant anti-windup compensation compensator design, the proposed scheme in this paper depends on the time-varying parameters to reduce the conservatism in obtaining the best performance of the closed-loop system subject to actuator saturation. The estimation of the system performance under the given parameter-dependent compensation gain is also formulated to a linear matrix inequality (LMI) problem, and hence is numerically tractable. The design of the parameter-dependent anti-windup compensator is formulated and solved as an iterative optimization problem with LMI constraints. Numerical examples are presented to illustrate the effectiveness of the proposed design technique.
