Abstract :
Switched interval systems are a class of hybrid systems. They own features of switched systems and interval systems. Under arbitrary switching signal, fault detection problem of switched interval systems is studied using common Lyapunov function approach in this article. Through the interval matrix equivalent transformation, switched interval systems are turned into a class of linear switched systems with uncertainty. The existence conditions and solvable conditions of robust fault detection filters are given. Conditions are represented in the form of LMIs. Finally, a simulation example is used to verify the validity of method.
