POSITION CONTROLLER OF MOTOR

摘要

PROBLEM TO BE SOLVED: To provide a position controller of a motor capable of adjusting a control parameter in a short period of time with high responsiveness, without measuring in advance the frequency characteristics of an object to be controlled that has a resonance frequency.

SOLUTION: The positional controller of a motor is equipped with a plurality of control parameter sets in advance which contain at least a proportional gain of a positional control part and that of a speed control part. Selecting a set and measuring a response state of a motor to the positional instruction when the motor is controlled using the control parameter of a selected set are sequentially performed. A desired single set is selected according to a measured response state. A set of selected control parameters is established and the control parameters are changed as a set.
