Gain-scheduled control of switched systems subject to actuator saturation

Abstract

A new technique is presented for the design of gain-scheduling controllers for switched systems with actuator saturation. By using the parametric Lyapunov equation-based approach and the invariant set theory, we develop a switching strategy of the whole system and propose a gain scheduling approach to increase the design parameter online. Then the closed-loop system is proven to be exponentially stable. Numerical simulations show the effectiveness of the proposed gain scheduling approaches.
