Abstract
A MGECU in a control device mounted on a vehicle has a feedback control section, a correction torque calculation section, an instruction torque calculation section. The feedback control section calculates a torque to be used for performing a feedback control of an actual rotation speed to follow a target rotation speed. The correction torque calculation section calculates a correction torque based on a change rate of the target rotation speed and inertia of a rotary body which includes the motor generator. When the target rotation speed is changed to decrease a difference between the target rotation speed and the actual rotation speed, the correction torque calculation section reduces the correction torque. The instruction torque calculation section adds the torque calculated by the feedback control section and the correction torque calculated by the correction torque calculation section in order to obtain the instruction torque to be used for the motor generator.
