Integrated fault detection and control design for continuous-time switched systems under asynchronous switching

摘要

This paper focuses on the integrated fault detection and control design (IFDCD) problem for continuous-time switched systems under asynchronous switching. Main goal is to design an observer by using piecewise Lyapunov function, H infinity control technique and average dwell time approach. In addition, switched controllers are designed such that the closed-loop switched system is asymptotically stable. The designed controller/detector are assumed to be asynchronous with the original systems. The admissible solution of the IFDCD problem is obtained by solving linear matrix inequalities (LMIs). Finally, to illustrate the applicability and the effectiveness of the proposed method, a solution is designed for two different case studies of boost converter and highly maneuverable aircraft technology.
