Title:
NON-LINEAR TYPE SERVO CONTROL METHOD
Document Type and Number:
Japanese Patent JPS6442713
Kind Code:
A
Abstract:
PURPOSE:To shorten the time required for positioning, and to facilitate the adjustment of a servo system by calculating a non-linear command speed for obtaining a gain of the servo system as it is, from the maximum set speed and the maximum set acceleration, inputting said speed, and executing the positioning. CONSTITUTION:The maximum speed and the maximum acceleration are set in advance, and from the deviation of a command position and the present position, and these maximum set speed and maximum set acceleration, a non-linear command speed for obtaining the gain of a servo system as it is calculated, this command speed is inputted to the servo system concerned, and positioning is executed. Since the non- linear command speed for obtaining the gain of the servo system as it is calculated and used, the constraint of saturation is released substantially, and high speed positioning determined by the gain of the servo system can be executed. Also, since it many suffice that at least two elements of the maximum speed and the maximum acceleration are set in advance, anybody can optimize the servo system. Moreover, by allowing the maximum acceleration which has been set, to coincide with the maximum acceleration peculiar to the servo system, both the acceleration and the deceleration are controlled to the same acceleration.
