Model based control system design has been developed in many fields based on the dynamics of the accurate plant model. However, the desired control performance is not achieved if the modeling error is not small. To overcome this problem, we have proposed a compensator to minimize the gap between an actual plant and its nominal model. The proposed compensator is composed of its plant model and an error feedback component. It is difficult to apply the compensator for non-minimum phase plants because of its control structure. In this paper, a parallel feedforward compensator is used to overcome the non-minimum phase characteristics. The effectiveness is shown by numerical examples.
