Conclusion
This study discussed a fault detection filter design for switching nonlinear stochastic systems using the event-triggered strategy. To simultaneously enhance the interference suppression ability and fault sensitivity of the fault-detection mechanism, a weighted mixed H−/H∞ fault detection filter was proposed. By choosing the convex Lyapunov function method and defining appropriate difference operators, we have researched the desired fault-detection filter and provided a sufficient condition about the existence in Theorem 1. The proposed results can be extended to many directions, such as systems with packed loss [5] and multiple nonlinear systems [6, 7].
