Abstract :
This paper considers robust H∞ filter design based on the exponential stability method for uncertain networked control system with networked delay, packet loss and random sensors fault. First, a set of stochastic variables are used to model the fault status of the sensors. It should be noticed that not only the fault are mentioned above, but also the uncertainties of the fault rate estimation are considered. Using the exponential stability method, sufficient conditions for the robust mean square stability are obtained, and the filter is also designed. Finally, a numerical example is given to demonstrate the efficiency of the proposed approach.
