Abstract
In controlling a motor in a device which drives a mechanism using the motor as a power source, in executing driving, an ideal profile of the driving is generated in accordance with a target position and a preset initial parameter, driving of the motor is controlled in accordance with the profile, the value of the initial parameter is evaluated at the end of driving, and the value of the initial parameter is changed in accordance with the evaluation result. High-speed accurate position control can be achieved independently of the characteristic of an individual motor to be used.
