Predictive control of networked control systems based on event-triggered

Abstract

Abstract.A novel structure of networked control systems which incorporates output feedback predictive control and event-triggered communication scheme in a unified model based on the networked control system with packet loss is proposed in this paper. The load of communication channel is relieved by event-triggered communication scheme, and the packet loss is compensated actively by predictive control. Then, the stability criterion which can guarantee the asymptotic stability of the closed-loop system is established and output feedback controller gain is obtained using the approach of a common quadratic Lyapunov and linear matrix inequality based on this model. A simulation example is given to demonstrate the effectiveness of the proposed method. The whole improvement of quality of performance and network quality of service is realized.
