<p>PURPOSE:To suppress the fluctuation of the revolutions of an engine, by turning a generator load means ON in the stroke to increase the instant rotating speed of the engine, and OFF in the stroke to decrease the speed, and by controlling the ON time according to a speed deviation. CONSTITUTION:By a generator load controlling circuit 13, according to a deviation between the rotational frequency signal N and the desired rotational frequency Nk of an engine 12, a load working on a generator 11 is ON/OFF- controlled. By the generator load controlling circuit 13, the generator load is turned ON in the combustion stroke to increase the instant rotating speed of the engine 12 and is turned OFF in the other stroke to decrease the instant speed. When the deviation between the rotating speed N and the desired rotational frequency Nk is larger than a set value, the ON time of the generator load is subtracted by a correction quantity. As a result, the fluctuation of the rotational frequency of the engine can be suppressed.</p> |
