Networked control system time-delay compensation algorithm based on predictive control

According to the problem of random time-delay resulting in performance degradation of the networked control system(NCS),aparticle swarm optimization(PSO)least square support vector machine(LSSVM)method is used to establish an NCS time-delay prediction model and predict the future time-delay.At the same time,the fast implicit generalized prediction algorithm is used to compensate the random time-delay in the NCS.The simulation results show that the PSO optimized LS-SVM algorithm has a high prediction accuracy for the random time-delay.Meanwhile,fast implicit generalized prediction control(GPC)can make the output of the system track the reference trajectory well and ensure the good control effect of the system.
