Stabilization Of Semi-markovian Systems With Actuator Saturation Based On Event-triggered Mechanism

This article addresses the stabilization of semi-Markovian jump systems with actuator saturation under the event-triggered mechanism.The third chapter studies the eventtriggered fragile stabilization and the H? performance problem of the semi-Markovian systems with actuator saturation.Due to actuator degradation and numerical round-off errors,non-fragile control is proposed.Meanwhile,the saturated nonlinearity is considered in the controller design process,which makes the controller designed more practical.Furthermore,the improved event-triggered scheme is utilized for reducing transmitting unnecessary sampled data to the network and saving communication cost.By establishing appropriate Lyapunov-Krasovskii functional that depend on model information and using some free-weighting matrix techniques,the new sufficient conditions for ensuring the stabilization for the given system are obtained.In Chapter 4,we talk about the semi-Markovian jump systems which include stochastic uncertain terms and saturated nonlinearity.Using the event-triggered mechanism and the way similar to Chapter 3,we give the conditions for the system to achieve stabilization in a finite time.Finally,numerical simulations are provided to verify the validity of our results.
