ScholarBank@NUS Repository. | Abstract: | The objective of this dissertation is to provide new, effective and practical control algorithms to improve the performance of hard disk drives (HDDs) and servo track writing (STW) servo system for the development of fast and high storage density HDDs. In order to increase the track density of our STW platform, an enhanced sensitivity function shaping technique based on the generalized Kalman-Yakubovic-Popov (KYP) lemma has been developed. As for improving the present HDD servo control technology, a unified control scheme (UCS) for high performance track-seeking and track-following in HDDs. Other than UCS, two more new control algorithms which can be designed and implemented using an b | URI: | http://scholarbank.nus.edu.sg/handle/10635/15873 |
