A motor generator (12) selectively performs a power generation operation and an assisting operation. A torque transmission machine (13) performs mutual transfer among a torque of an engine (11), a torque of the motor generator, and a torque to be applied to an external load of the engine. A speed sensor measures the rotating speed of the engine. A control device (30) controls the engine and the motor generator. The control device stores a speed command value for the engine, calculates the torque generated by the motor generator based on the power required for the external load, to perform the torque control of the motor generator, and performs the speed control of the motor generator based on the difference between the rotating speed measured by the speed sensor and the speed command value. The torque control and the speed control of the motor generator can be switched. |
