ABSTRACT:
An object of the invention is to provide a servo control device capable of making zero the positional deviation the positional deviation at a constant speed as well as the positional deviation at a constant acceleration or at constant acceleration and jerk, thereby providing a high-precision follow-up response.In order to solve this problem, the servo control device according to the invention includes a position controller (3) for generating a speed command that matches the motor output with a target position, a feed-forward controller (4) for adding a signal obtained by multiplying the differential of a target command by a gain and a signal obtained by multiplying the second-order differentiation of the target command by a gain and generating a speed feed-forward signal, and a speed controller (2) for performing I-P or PI control of the motor (1).
