Linear Model Following Control Systems Based on Reduced Models

A linear model following controller based on a reduced-order plant model is presented in this paper. The reduced model is composed of two submodels that characterize the dynamics during the transient and the steady states. The order of the controller is minimized without deteriorating the system performance. In addition, the proposed modified linear model following controller, which uses the output as the feedback signal, can be easily implemented. Some simulation and experimental results are given to demonstrate the effectiveness of the proposed controller.
