Adaptive event-triggered communication scheme for networked control systems with randomly occurring nonlinearities and uncertainties

This paper proposes a novel adaptive event-triggered communication scheme for networked control systems (NCSs) with randomly occurring nonlinearities and uncertainties. Firstly, an adaptive event-triggered communication scheme for NCSs is proposed, which can adaptively adjust the trigger parameter with respect to the dynamic error to save the limited network resources while ensuring the desired control performance. Secondly, an integrated model of the studied system is built under consideration of the network-induced delay, adaptive event-triggered communication scheme and randomly occurring nonlinearities and uncertainties in a unified framework. Then, sufficient stability criterion to judge the mean-square sense asymptotically stable and stabilization criterion to co-design the parameters of the communication scheme and controller are obtained for the system under consideration. Finally, two examples are given to illustrate the effectiveness of the developed method.
