In this paper, we address the state/fault estimation and observer-based control issues for switched systems with sensor faults. The main objective is to estimate sensor faults and compensate for their effects on the system state estimation, and then stabilize the switched system by the estimated state feedback. Applying the mode-dependent average dwell time (MDADT) concept and the Lyapunov stability theory, a new separation principle is developed, which allows formalizing the observer-based controller design in the form of linear matrix inequalities (LMI) instead of bilinear ones.

Main goal is to design an observer by using piecewise Lyapunov function, H∞ control technique and average dwell time approach. In addition, switched controllers are designed such that the closed-loop switched system is asymptotically stable.
