Servo control system is adopted for the position, angle and speed control. The PID and the optimal servo control theory are in common use as the controller design. These control system will process by only the present reference input. Therefore, the system begins to work after the reference input was a change. In this paper, we remarked the preview control theory in order to improve the tracking performance for the servo control system. The simulation and experimentation performed in order to evaluate the effectiveness of the preview control system by adopting to the control problem for a ball and beam.
