Abstract

This paper is concerned with a new combination of the event-triggered scheme and the networked predictive control technique for the networked control systems (NCSs) subject to time delays in both sensor-to-controller and controller-to-actuator channels. Firstly, the output-based Luenberger observer is designed for the considered NCSs. Secondly, in order to stabilize the NCSs, the model-based networked predictive control technique is proposed to compensate for the network-induced two-channel delays. Next, two different analysis frameworks are presented, and sufficient conditions for the asymptotic stability of the resulting closed-loop systems are obtained, respectively. Particularly, the proposed event-triggered scheme based on the measured outputs and the state predictions have considerably reduced the times of data transmission over the bandwidth-limited communication networks. Finally, an example of the buck DC-DC converter system is provided to demonstrate the effectiveness of the developed method.
