摘要
In an actuator drive control device for an active vibration isolation support system, accumulated time of eight time intervals tn of crank pulses which are outputted at every 15 degrees of a crank angle in a vibration period corresponding to 120 degrees of the crank angle, and average accumulated time shown by a straight line connecting a start point and an end point of the line of the accumulated time are calculated. Eight deviations Δtn are calculated by subtracting the average accumulated time from the accumulated time. A variation waveform of the deviations Δtn corresponds to a variation waveform of the time interval tn of the crank pulses attributable only to the engine vibration with the influence of a variation in the engine rotational speed Ne being eliminated.
