本文提出鎖相迴路設計步進伺服系統之技術，利用多重取樣方式設計微電腦爲基礎之脈冲汲式控制器，並建立系統模式進行穩定性之分析與電腦模擬。本文亦設計與實現系統原型以驗證理論分析結果與檢視所提出系統之功效。利用此一鎖相技巧可得到一個0~50 cm之實際位置控制系統，其解析度可達10μm。
A stepping position servo system based on phase-locked loop is proposed. A novel microcomputer-based pulse pump controller (PPC) using multirate sampling technique is exploited. The system models are constructed for stability analysis and computer simulation. A prototype is designed and implemented to verify the theoretical analysis and examine the performance of the proposed system. Position and speed responses of a realized system for 0-50 cm movement with 10mm resolution is obtained.
