Predictor-based event-triggered control for nonlinear cyber-physical systems under channel-induced delay

This article addresses the issue of designing a predictor-based event-triggered control strategy for cyber physical systems with channel induced delay over the controller – actuator portion of the communication channel. To deal with the conservatism posed on the system performance and stability by the channel delay a model-based predictor is first designed and a control policy is subsequently formulated using the predictor states. This predicted version of the control policy effectively mitigates the ill effects of the channel delay. To ensure the optimum utilization of the channel resources and to reduce the computational burden an event-triggered version of the control policy is devised. The event-triggered control proposed in this work ensures the Zeno free behavior of the system and the Lyapunov-function-based analytical developments reflect the uniform ultimate boundedness (UUB) of the state variables with the prescribed system performance. The validation of the effectiveness of the presented control scheme is illustrated with the help of numerical simulation.
