Event-Triggered Networked Predictive Controller Design for Linear Systems with Communication Delay

This paper is concerned with the controller design for networked control systems (NCSs). A novel event-triggered networked predictive control scheme is proposed to compensate for the network-induced delay and save network bandwidth. The closed-loop system is modeled as a switched system with time-varying delay. By constructing a common Lyapunov function, a sufficient stability condition is derived and presented in terms of linear matrix inequalities (LMIs). In order to prove the validity of the proposed method, both a simulation and an experiment are carried out. Both simulation results and experimental results show that this method can compensate for the network-induced delay actively and reduce the burden of the network significantly.
