Simulation and Analysis to Control Algorithms of the Large Time-delay System based on Simulink

摘要：

　　Because of the universal existence of time-delay phenomenon in industrial process control,this paper analyzes the characteristics of two kinds of control methods,discusses the relations between general control algorithm and Smith predictor compensation,and simulated studies the mismatch of model,the change of delay time and the effect of the disturbance to the system.Simulation results show that:improved Smith predictor controller has the advantages of fast response and low overshoot.Especially in the case of the mismatch of model,it has better robustness and stronger anti-interference ability.The improved Smith predictor brings a good quality,which has little sensitivity to the model parameters.It provides a kind of method to overcome the time delay.
