Abstract :
This paper is concerned with the problem of fault detection for networked control systems (NCS) with uncertain time-delay. By using delta operator, a new model is proposed. Then, based on the traditional robust fault detection filter and linear matrix inequality (LMI) approach, the system fault detection can be converted to the solution of the robust control problem. The sufficient conditions for the existence of the gain of observer are given in terms of LMI approach. Finally, a numerical example is provided to show the effectiveness of the proposed design method.
