摘要

本研究之目的在於提出一套混合變轉速系統(Hybrid variable speed system; HVSS)之創新概念及其系統化分析與設計方法，使其具有精確度高、調整容易、花費低、控制容易、響應快、所需馬達功率小、具飛輪效應、及輸出功率大等優點。首先，探討混合變轉速系統的構造與特性，以歸納訂定出設計需求與限制，並使用圖形理論進行系統構造合成，且有系統地找出所有可行的系統構造。接著，提出混合變轉速系統之轉速設計方法，可依照所需輸出變轉速進行混合變轉速系統之設計，以求出馬達輸入轉速。然後，以半閉迴路控制架構為混合變轉速系統之模型，並進行PID控制法、相位領先補償法、及基因演算法等控制器之設計與分析，以求得較佳控制器類型及參數。最後，進行實例設計，實際製作雛型機與建立一套實驗系統，以驗證理論設計分析之正確性。由實驗結果顯示，系統之輸出變轉速與設計極為吻合。因此，所提之混合變轉速概念是極為可行的。

This work aims to propose an novel method of the hybrid variable speed systems (HVSS), such that it has the advantages of higher reliability, easier adjustibility, lower cost, easier control, faster response, lower input power, higher power transmission, and with flywheel effect. First, the design requirements and design constraints are summarized by investigating the characteristics of HVSS structures. Then, the atlas of feasible structure is systematically generated by performing structural synthesis using graph theory. After that, the kinematic design method for the HVSS is proposed, then the input trajectory of the motors can be generated by the method. Moreover, the semi-closed-loop control architecture is adopted as the system model, and the design and analysis of controllers, including PID control, phase lead compensation, and genetic algorithms are conducted. Finally, two examples are given to illustrate the design process, a prototype machine is made, and an experimental setup is established to verify the feasibility and the effectiveness of the proposed design and analysis approaches. The experimental result show that the output of the proposed HVSS agrees well with the theoretical design. Therefore, the proposed system as well as its design and analysis approaches are feasible.
