Abstract: The robust reliable control design problem for uncertain systems with timevarying state delay as well as actuator failures in the input channels was discussed. A sufficient condition was established such that the closedloop system quadratic stability is satisfied for both the normal system and the system with possible actuator failures. The condition is a delaydependent one. A reliable state feedback controller was synthesized within the framework of linear matrix inequalities. The simulation results demonstrate the efficacy and validity of the approach.
