Output feedback control for uncertain linear systems with faulty actuators: An average dwell-time method

Abstract

This paper deals with the problem of output feedback stabilization for a class of uncertain linear systems with actuator failures. When actuators suffer "serious failure" - the considered closed-loop system is unstable, based on average dwell time scheme, under the condition that activation time ratio between the system without actuator failure and the system with actuator failures is not less than a specified constant, the dynamic output feedback controllers are derived in terms of linear matrix inequalities (LMIs) such that the resulting closed-loop system is exponentially stable. Finally, a numerical example illustrates the effectiveness of the proposed approach.
