Abstract
Control of a motor in a device in which a mechanism is driven using the motor as the power source is achieved by providing velocity servo-control means for outputting first command information regarding the motor based upon a preset velocity profile and information relating to velocity of the mechanism, and position servo-control means for outputting second command information regarding the motor based upon a preset position profile and information relating to position of the mechanism. A motor driving signal is generated, based upon the first and second command information, in a region in which the mechanism is to be accelerated in the velocity profile. As a result, target-velocity attainment time is shortened and velocity fluctuation after attainment of the target velocity is reduced.
