PURPOSE:To minimize the responsive time of a servo so as to improve its following performance, and obtain a highly reliable simple following control method by driving the servo always by optimal regulating speed. CONSTITUTION:A servo system is controlled by a position or an angle, and also forced to follow a target value. In the servo system, there are provided a stroke 11 for setting the operational condition of the servo according to the acting direction and acceleration/deceleration direction of the servo 2, a stroke 8 for calculating a deviation of the present position from the target position of the servo and a stroke 10 for calculating the speed of the servo 2. Also there are provided strokes 9 and 12 in which operation of the servo 2 is displayed on the phase plane of optimal acceleration/deceleration curve group which is found out by relation between the displacement and speed, while the phase plane is processed as the acceleration/deceleration speed table, and then a plurality of mode are set from operating condition of the servo 2 on the basis of the acceleration/deceleration speed tables, and the servo 2 is transferred between the plurality of modes, while the servo 2 is operated along the optimal acceleration/deceleration curve. |
