The purpose of this work is to propose a scheme to stabilize the predictive control systems in the practical stability serse. In the paper, the authors dealt with a general discrete predictive control system xj = f( xj , uj ) by using the Lyapunov direct method combining with receding-horizon control technique,and presented a new condition to guarantee the practical stabilization of the systems. With the proposed results, one can design the optimal controllers easily to practically stabilize the predictive control systems.
