In this article, a systematically discrete dynamic sliding surface design methodology based on the model reference approach is presented. The key concept of this new approach is converting the sliding mode regulating problem to a sliding mode tracking problem and approximate the one-step deadbeat response by series of smaller deadbeat responses. The transient characteristic of the control system is determined by the pole of a first-order reference model, while the chattering suppressing ability depends on the forgetting constant of the forgetting factor. The AC servo motor positioning problems were simulated to illustrate the performances of the proposed method. Simulation results show that the proposed method possesses good characteristics such as model following and chattering suppressing. (C) 2004 Published by Elsevier Ltd.
