Necessary and sufficient conditions are given for arbitrary pole placement of the state feed back model predictive control (SPC) systems. Based on the state space model, the design procedure is introduced step by step for choosing the design parameter--the prediction horizon. By introducing new design parameters such as control move damping coefficient and state feedback weighting fact, the poles of the closed loop predictive control systems can be assigned arbitrarily. The design parameters can be adjusted easily on line. Therefor the predictive model can be widely used. The closed loop predictive control system has good performance and robustness.
