INTELLIGENT FUZZY CONTROLLER OF TRACKING A HARD DISK DRIVE ACTUATOR USING APPROACHING INDEX SWITCH Ayman A. Aly (1), Shehab R.Tawfeic (2) (1) Assiut University, Assiut , Egypt.

Abstract: In this paper a new switching algorithm of approaching index using alternatively the advantages of the fuzzy logic control and the classical proportional derivative PD control was proposed. It can decide if the system is approaching the final destination or not, to select the adequate controller output policy to be applied to the system during each control period. On the application side, As the need of high capacity, small size data storage devices is increasing, It is hardly need to find controller performance able to meet the challenging specifications for Hard Disk Drive (HDD). The performance of the proposed switching control algorithm is illustrated with simulation model of a voice-coil-motor (VCM) actuator of a HDD. The proposed controller shows that it has mach better performance than those of the PD controller. The resulting system has smaller rise time, minimal overshoot and faster settling time.
