Abstrakt: This work presents the problem of interval estimation and passive fault tolerant control (FTC) for discrete-time switched linear systems (SLS). The considered systems are affected by disturbances, measurement noises and actuator faults. The uncertainties are supposed to be unknown but bounded with a priori known bounds. Based on a state feedback, a FTC is designed to maintain desired performances and preserve stability conditions in presence of actuator faults. The control law is designed by means of interval observer structure, guaranteeing interval estimation, where the stability conditions are expressed in terms of linear matrix inequalities (LMIs). Numerical simulations are provided to demonstrate the efficiency of the proposed method.
