Adaptive event-triggered control of a class of nonlinear networked systems

This paper investigates an adaptive event-triggered communication scheme (AETCS) for a class of networked Takagi-Sugeno (T-S) fuzzy control systems. The threshold of event-triggering condition has great influence on the maximum allowable number of successive packet losses. Different from the conventional method, the threshold, in this study, is dependent on a novel adaptive law which can be achieved on-line rather than a predefined constant, since the threshold with fixed value is hard to suit the variation of the system. The stability and stabilization criteria are derived by using a new Lyapunov function. Finally, an example is provided to demonstrate the design method.
