臺灣博碩士論文加值系統

在磁浮輸送系統的相關研究領域中，大部分的研究議題都是集中在控制律的求解與硬體控制器的實作問題上。本論文從另一角度出發，經由特定的設計與磁鐵安裝方式，使磁浮軌道與載具的運作具有部分之穩定性，以減低磁浮輸送系統整體控制問題的複雜度。首先提出一設計概念，藉由磁浮軌道中永久磁鐵的特定排列方式，期使載具得以在準穩定的情形下作有限自由度之運動。其次依前述之設計理念實作一概念測試平台，以驗證實體上之之可行性。同時運用有限元素分析之工具，針對實作平台內部之磁場分布特性與載具之受力情形作一探討。最後透過現有平台與有限元素分析的資訊，發展出改進現有系統的設計準則與方法。

In the related research field on magnetic levitated transportation systems, most issues were focused on their derivative control laws for control system hardware implementations. In this thesis, another viewpoint of approach is proposed via a specific design and arrangement of permanent magnets on a magnetic track frame and levitation vehicle. This configuration is considered to reduce the complexity and difficulty on the control system design task. A specific arrangement of permanent magnets configuration inside the track frame is analyzed for a vehicle to move along the track under quasi-stable condition. The proposed concept-proofing track model was build and tested to verify the correctitude of the proposed idea. The model was analyzed with finite element analysis (FEA) tool to look into the profile of magnetic field distribution inside the track and to figure out the exerting force and torque on the vehicle model. With the information collected form FEA and practical operation of the model system, some design criteria and recommendation were obtained for the system feasibility and performance improvement to the current system.
