Event-triggered Switching Filter Design for Uncertain Nonlinear Networked Systems with Time-varying Delay

This paper addresses the event-triggered (ET) switching filter for a type of uncertain nonlinear networked systems subject to time-varying delay. Nonlinear system is described by Takagi-Sugeno (T-S) fuzzy model with unknown membership functions. For the purpose of saving network communication resource, an ET scheme is introduced between the plant and the filter but it causes the asynchronous problem of premise variables. To solve these problems, a switching method is adopted which uses the boundary information to build the switching rules. In addition, according to Lyapunov function and linear matrix inequality (LMI) technique, the sufficient conditions for H-infinity performance and stability are obtained. Finally, a simulation is provided to demonstrate the feasibility and merit.
