Abstract :
Implementation of a disk drive servomechanism using a digital signal processor (DSP) is discussed. A seek controller for voice coil motor (VCM) which eliminates the control chattering and reduces the high frequency flexible modes excitation is discussed. The pros and cons of implementing a disk drive servomechanism using DSP are discussed. Results are presented which show the effectiveness of the controller
