초록
This thesis presents a design methodology of a Digital Servo Signal Processor for high speed CD-ROM drive systems. The proposed Digital Servo Signal Processor enables us to develop CD-related systems for the very high speed applications and is one of the key components of the CD-ROM systems. The proposed center compensation servo control is newly built for a actuator shaking due to the fast response of a step motor when it jumps to a long distance. From experimental results, we can see that the performance of the control system is improved greatly. The proposed servo algorithm shows a shorter setting time including a pull-in time and a faster access time.
