摘要

This paper investigates the problem of fault detection for networked control systems with time-varying sampling period under the condition of communication constraints. Considering the factors of delay and limited communication, the residual system can be modeled as a parameter-uncertain discrete system by using the parameter uncertainty-based approach to deal with the time-varying sampling periods. The sufficient conditions for the residual system to be stochastic stable and meet the H-infinity performance are given in terms of the Lyapunov stability theory and linear matrix inequality approach. The design method of the fault detection filter is also provided. A numerical example is given to illustrate the effectiveness of the proposed method.
