Research of Networked Control System Based on GPC Algorithm

Aiming at a kind of networked control system(NCS) which contains random time delay,the paper designed a controller based on time delay compensation and generalized predictive control(GPC) algorithm. The controller calculated time delay of sensor-to-controller by analyzing time stamp of data packet, then it obtained the current state and output by time delay compensation and used GPC algorithm to calculated control signal. Simulation result proved effectiveness of the controller.
