摘要：

This paper deals with the problem of finite-time fault detection filters designing problem for switched systems with all subsystems unstable. Using the average dwell time method, a switching rule ensuring stability is given. The filter design is converted to the finite-time -gain analysis. Then, sufficient conditions are raised to ensure finite-time boundedness and -gain property by LMIs. Discretised Lyapunov function is introduced for the theoretical analysis. In the end, an example is listed to attest the general validity of the raised way.
