Reliable H{sub}∞ Controller Design for a Class of Uncertain Linear Systems with Actuator Failures

摘要

This paper is concerned with the reliable H{sub}∞ controller design problem for uncertain linear systems against actuator failures. In the design, the H{sub}∞ performance of the closed-loop system is optimized during normal operation (without failures) while the system satisfies a prescribed H{sub}∞ performance level in the case of actuator failures. Single and parameter-dependent Lyapunov function approaches are applied in designing suboptimal reliable H{sub}∞ controllers. Simulation studies are presented to demonstrate the effectiveness of the proposed design procedures.
