Feed Forward Control to Enhance CD Skip Performance 981152

This paper considers the design, implementation and validation of Feed Forward Control for a Compact Disk mechanism. The design objective is to increase the ability of the CD-mechanism to withstand external mechanical disturbances. For the research discribed an accelerometer has been used to measure the base-acceleration. This signal is filtered and added to the focus servo loop. The reduction of the servo error signal has been used to indicate the effectiveness of the feed forward.
