Abstract :
Considers multi-rate estimator design and proposes very simple and practical methods to improve the performance of multi-rate estimators. The proposed methods are applied to disk drive servo system design. Experimental results are presented to show applicability of the proposed design techniques. Noticeable performance improvement is observed with the proposed multi-rate estimator especially during seek motion of a disk drive actuator
