| 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. |
