Abstract
Discusses the intersample ripple problem in multirate control design of a hard disk drive (HDD) servo system. An intersample ripple-free multirate control scheme is presented. Based on the conventional multirate approach, a constraint on the controller parameters is introduced in the new scheme. The constraint is to force the multirate control inputs to converge to the same constant level so as to eliminate the intersample ripple in the system output.
