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