Master–Slave Synchronization of Switched Nonlinear Systems Based on Quantization and Switching Event-Triggered Strategy

The present study focuses on the master–slave synchronization issue for switched nonlinear time-delay systems based on quantization and switching event-triggered strategy (ETS). The logarithmic quantizer and the switching ETS that is represented by a transition between the periodic sampled-data control and the general continuous ETS are adopted to improve resource utilization and adjust data transmission. According to the event-triggered sampled signal, the synchronization error system with asynchronous switching signal is modeled. In virtue of multiple Lyapunov functional approach, the sufficient conditions are obtained to guarantee the error system is exponentially stable by developing some linear matrix inequalities (LMIs), from which the synchronizing controller is orchestrated. Lastly, the reliability of the proposed methods is illustrated by numerical simulations.
