Internal Model Control with a Dynamic Model Compensator

In this paper, a dynamic model compensator is proposed to decrease the mismatch be- tween the model and the process, so as to improve the performance of the internal model con- troller when a time-varying process in handled. As the dynamic model compensator is de- signed based on the hyperstability theory proposed by V.M.Popov, the stability of the struc- ture of the model compensation is guaranteed. The experiments of simulation show that the approach proposed by the paper is rather robust and can deal with the system where the pa- rameters may vary within a certain extent. The comparision demonstrates that the perfor- mance of the internal model controller is improved.
