Abstract :
This paper applies a novel adaptive feedforward compensation (AFC) algorithm for runout cancellation on voice coil motor (VCM) actuator servo system. The parametric update laws of this adaptive algorithm can be precisely deduced. The AFC controller can attenuate selectively the intended harmonic runout without amplifying other harmonics. The testing results in time domain and frequency domain show that this scheme is effective in dealing with runout
