Event-triggered non-fragile finite-time H∞ control for semi-Markovian jump systems with actuator saturation

This paper addresses the problem of finite-time H-infinity stabilization for semi-Markovian systems with actuator saturation via dynamic event-triggered scheme. 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 finite-time H-infinity stabilization for the given system are obtained. Then the gain matrices of the controller can be also designed. Finally, a simulation example is provided to verify that the results we get are effective. (C) 2020 The Franklin Institute.
