Reliable control for switched systems with time delay and mixed fault of actuator

Based on mixed fault for actuator, this paper is concerned with reliable control problems for systems with time delay. Mixed fault is discrete fault model and continuous fault model coexist in a system. The proposed method not only quotes the general model but also combines reliable control with switched system, making full use of advantages of both systems. It can save much energy for reliable controller in practical. The paper has given a sufficient condition for the existence of reliable controller for general fault model and switched law are derived via the linear matrix inequality approach and convex combination method. Numerical examples are given to show the efficiency of the method.
