Abstract
Networked control system improves system flexibility, control efficiency and reduces component installation and maintenance cost, however, network-induced time delays and packet dropouts may degrade or even destabilize the system. This paper proposes a novel predictive observer based control strategy to solve this problem. Random time delays and packet dropouts are considered in a more natural way without any limitations in both backward and forward channels. A mixed event-time driven predictive controller is designed to effectively compensate the long delays and lost packets. Stability of newly developed NCS model is analyzed. Simulation results show the effectiveness of the proposed strategy and guarantee the performance of the closed-loop system.
