The Research of Network Closed-loop Control Based on the Model Predictive Control

Because of the uncertainty of network time-delay in the remote control system based on the Internet, - which will bring greater difficulty to the design of the closed-loop control system.The influence of the network transmission delay on the closed loop control system is researched,the predictive control method based on the neural network is proposed in the paper.The method provide the feasibility to solve the random delay of network control system.The simulation results show that the model can effectively substitute the actual network in Internet-based closed loop control system research under time-delay condition;the methods used in the modeling,due to the virtue of speediness and exactness,is capable of learn and predict the network time-delay on line,this gives a new idea in Internet-based remote closed-loop control.
