Robust Fault Tolerant Control for Uncertain Switched Systems with Time Delay

This article concerns the problem of robust fault tolerant control for uncertain switched systems with time delay in the presence of actuators faults. Based on an observer synthesis, a new technique of fault detection, localization and reconfiguration is established to maintain asymptotic stability when an actuator fails temporary or permanently. The design problem is formalized in the form of linear matrix inequalities. To reduce the conservatism of the obtained conditions, slack variable technique is used. To demonstrate the effectiveness of the proposed approach, simulation results are given in terms of two examples and comparative study.
