<p>PROBLEM TO BE SOLVED: To converge to a target rotational frequency with high response, and to stably keep the target rotational frequency.SOLUTION: A control unit 1 determines ranges of difference between a target rotational frequency and an engine rotational frequency, not operating electronic throttles 11, 12 respectively disposed in cylinders, as a first dead zone and a second dead zone respectively to the electronic throttles 11, 12, determines whether the difference between the target rotational frequency and the engine rotational frequency is in the dead zone or not, for each of the electronic throttles 11, 12, inhibits an operation of the electronic throttle on which it is determined that the difference exists in the dead zone, and operates the electronic throttle on which it is determined that the difference is over the dead zone, while determining a control gain to the electronic throttle according to the magnitude of the difference.</p> |
