Abstract
Head to disk striking is an essential problem in the servo track writing process caused by less dynamic response control. This paper describes head loading control for the hard disk drive process using model reference adaptive (MRAC) technique, in order to decrease the occurrences of the head striking. The introduced technique, discrete time model reference adaptive has an adjustable control mechanism to decrease the deviation of a system output from the output of the reference model so that increase reference tracking performance. The experiment results implemented in self-servo track writer illustrated that the proposed controller design can achieve the effective control performance comparing with the conventional PID control.
