| Abstract: | The problem of robust and reliable control design for linear uncertain impulsive systems with both time-varying norm-bounded
parameter uncertainty and actuator failures was studied. The actuators are classified into two groups. One set of actuators
susceptible to failures is possible to fail, the other set of actuators robust to failures is assumed never to fail. The outputs
of the actuator failures are regarded as zero. The purpose is to design the state feedback controller such that, for all admissible
uncertainties as well as actuator failures occurring among a prespecified subset of actuators, the plant remains asymptotically
stable. A modified algebraic Riccati equation approach was developed to solve the problem addressed and a robust reliable
control law was obtained. An numerical example was also offered to prove the effectiveness of the proposed method.
