Abstract
In controlling a motor in a device which drives a mechanism using the motor as a power source, pre-driving of giving a predetermined driving parameter to the motor and driving the mechanism is executed. During the pre-driving, movement of the mechanism is monitored, and a command value to the motor, which is necessary for starting the mechanism, is obtained. Driving of the motor is controlled using feedback using the command value as the initial value of the driving parameter. High-speed accurate position control can be achieved independently of the individual difference in an object to be controlled and the frictional force of the mechanical portion or the difference in use environment.
