Abstract

Networked control system (NCS) is a kind of closed loop control systems where the sensors, the controller and the actuators exchange data through network. Because the networks, in which the band width is limited, are introduced in the systems, some new issues appear unavoidably. At present, the research of networked control system becomes a focus area in control engineering. According to the characteristics of NCS, incremental predictive functional control (IPFC) strategy with random long time delay in NCS is proposed in this paper. Based on the strategy proposed controller design is given, which realized the compensation of NCS time delay. Simulation experiments are carried out, and simulation results confirmed that perfect compensation effect is obtained in the long time delay NCS with the control strategy proposed in this paper.
