PURPOSE:To control the rotational frequency of a turbocharger so that an evil influence due to the increase of amplitude in the rotational frequency of resonance is prevented. CONSTITUTION:A dynamo-electric machine 3 is mounted on a rotary shaft 12 of a turbocharger 1. When the rotational frequency of the turbocharger 1 reaches the vicinity of a resonance point during acceleration, the dynamo-electric machine 3 is motor driven by a battery 5 as a power source to be accelerated and pass fast through the resonance point. The dynamo-electric machine 3 is operated to generate power in deceleration, reduce the turning force, and pass fast through the resonance point for reducing amplitude in the resonance point. |
