Abstract
Aiming at the random transmission delay problems in Wireless Networked Control System (WINCS), a compensating strategy of network delay is proposed based on an improved Dynamic Matrix Control(DMC). By introducing error rate between the reference output and the predicted output in the performance indicators of traditional DMC and rolling optimization, the strategy can calculate the optimal control increment sequence and predict the future output of the WINCS, and then an optimal control increment signal is chosen which is transmitted to the actuator in order to compensate for the random delay in wireless network transmission. A simulation model of WINCS is designed on the basis of the toolbox of TureTime and the simulation environment of Matlab/Simulink, and the control plant is DC motor. The simulation results show that the algorithm offers feasibility and validity for processing delay of the WINCS.关键词
