摘要： An apparatus for active vibration control of a hybrid electric vehicle including an engine and a motor is disclosed. The apparatus includes: a position sensor to detect position information of the engine or the motor; and a controller to select a reference angle signal based on a signal from the position sensor. The controller performs fast Fourier transform (FFT) analysis by generating a reference angle, extracts a vibration component of each frequency through the FFT analysis, generates a reference signal by performing inverse FFT, and performs active vibration control of each frequency by reflecting a basic amplitude ratio, an adjustable rate according to an engine load, and an engine torque to the reference signal.
