A predictive control method for networked control systems with random delay and packet dropouts

Abstract

For networked control systems (NCSs) with random delay and packet dropouts in feedback channel (sensor to controller) and the feedforward channel (controller to actuator), in this paper, a predictive control algorithm based on the theory of pseudo partial derivative (PPD) is used to compensate random delay and packet dropouts in process of the network transmission. Furthermore, the stability and convergence of the algorithm are proved. Finally, simulation results show that the proposed algorithm is reasonable and effective.
