Internal model control is a new developing control method in recent years, its principle analysis is very important in engineering application and theoretical research. From the structure of IMC, the article reveals the essence of internal model control, and then it proves that the system can not only achieve the no difference tracking for the step signal, also realizes the no difference control with the disturbance of step signal. This article introduces the internal model controller for the linear time-delay system and the method of IMC filter designing. Based on the simulation with Matlab, it shows the great robustness for the internal model control in the linear time-delay process, and has great value on application.
