    摘要: 本計劃分三年執行各項研究, 第一年進行尋軌與定位之強健適應控制法則設計, 及循軌伺服致動器與軌伺服致動器之互動研究, 第二年則進行音圈馬達應用於次世代高密度數位影音光碟機之研究, 第三年則使用晶片組實現所設計之控制電路, 並與其它子系統進行系統整合,作整組DVD之實體驗證。
    One of the most important criterion in evaluating the velocity performance of DVD is DVD's seek time. The major goal of this research proposal is to develop a high performance seek control system which is capable of reducing the DVD's seek time. Voice Coil Motor (VCM) can reduce the friction and speed up the movement of optical head; and hence, reduce the DVD's seek time. Therefore, our research will focus on studying the characteristics of VCM and its role in the whole seek servo control system. We'll investigate VCM's structure dynamical response and its robustness. Based on that, a robust control algorithm will designed to perform the seek operation. In addition, we will also work on integrating the fine actuator and coarse actuator to reduce the swing motion which greatly increase the seek time during the look seek motion.. An adaptive observer will be designed to estimate the state of the fine actuator and a robust adaptive controller will be designed to control the dual actuator (fine and coarse actuators) system. In the final, , we will build the real structure of the seek servo system for hardware emulation. The designed control circuit will be implemented in a chip and will be integrated with other subsystem to control the whole DVD system.
