Filed: 2018-03-26
Abstract: To control a driving force of a motor, which moves a movement object, according to a drive load.SOLUTION: When moving a movement object in the case relevant to an initial operation time, a driving force of a motor is controlled according to a previously prepared first velocity profile and movement object is moved. A first torque applied to the motor is determined in an acceleration region of the first velocity profile. A preset target acceleration torque and a first difference torque, which is a difference from the first torque, are determined on the basis of a maximum limit torque at a time of acceleration permitted for the motor. A first surplus power acceleration, which can be increased in the acceleration region, is determined on the basis of an inertia acting on the motor and the first difference torque. A second velocity profile, in which the first velocity profile is corrected on the basis of the first surplus power acceleration, is generated. When moving the movement object in the case irrelevant to the initial operation time, the driving force of the motor is controlled according to the second velocity profile, and the movement object is moved.SELECTED DRAWING: Figure 2
