<p>PURPOSE:To suppress the rotating fluctuation of an engine, by turning a generator load ON at an increasing point of engine speed timing, and OFF at a decreasing point, and by controlling the phase lead for the ON/OFF-position of the generator load at the time of increase in the rotation speed of the engine. CONSTITUTION:From an ON/OFF-control circuit 14, the output of a crank angle thetaon accommodated to the start of the combustion stroke to increase the rotating speed of an engine according to the rotational frequency N of the engine 12, and the output of a crank angle thetaoff accommodated to the start of the other stroke of the reduced rotating speed are generated. By a generator load ON/OFF-control circuit 15, a generator load is turned ON when the crank angle thetaE of the engine 12 coincides with the crank angle thetaon, and the generator load is turned OFF when the thetaE coincides with the crank angle thetaoff. Besides, by an ON/OFF-position correcting circuit 16, the crank angles thetaon, thetaoff are lead- angle-corrected when a speed fluctuation N comes to a specified value or more.</p> |
