Abstract

In this paper, an event-triggered fault-detection filter design for reducing communication actions in networked time-varying stochastic systems over a finite-time horizon is proposed. A coordinate transformation approach is exploited to achieve the purpose that the fault-detection residual is only sensitive to system faults while robust to additive unknown disturbances. This approach can transform the considered system into two subsystems, and the disturbances are removed from one of the subsystems. Furthermore, the optimal gain for each filter is derived, which applies to the optimization criteria of unbiasedness and minimum mean-square estimation error.
