Abstract :
An adaptive neural network (NN) controller is applied to the voice-coil-motor (VCM)-actuator of a hard disc drive (HDD). The controller can track asymptotically a given demand trajectory while compensating robustly for bounded friction and bias forces. It is shown practically that this controller is a good candidate for a track seek/following controller in hard discs.
