Improved hard disk seek time using fuzzy logic control

Fuzzy logic controllers exhibit many advantages over traditional controllers in applications involving systems with uncertain or highly complex dynamics. These controllers do not require a detailed mathematical model of the system, only an intuitive grasp of the system dynamics. Due to some of their inherent advantages, fuzzy logic controllers are finding applications in an increasing number of fields. This study applies a fuzzy logic controller to hard disk drive read/write head positioning. Performance analysis indicates reduced seek times compared to conventional disk drive control techniques.
