    Abstract: This paper has presented a control system for read/write (R/W) head position control of a hard disk drive (HDD) using model reference adaptive control (MRAC) integrating proportional integral and derivative (PID) algorithm. It is desired that the (R/W) head of a HDD be accurately positioned so as to maintain appropriate track during operation. A dy... Show More
