自發電阻尼驅動系統設計與控制之研究

現今工業時代，人口集中於都市中，運動的空間與時間逐漸減少，所以家庭用運動器材的成為健身運動的主要器材，再加上能源短缺的世界趨勢，發展自發電阻尼控制系統的健身器材則為相關業界的重要研究課題。本文針對節能產品的需要，進行自發電阻尼系統的設計與控制之研究，以健身腳踏車為實作標物，其主要架構有發電系統、阻尼系統與控制系統。發電機組主要研究高效率、低噪音的發電品質，並對相關理論與材料進分析與介紹；阻尼系統主要利用發電機的外轉子飛輪作為導磁體，並配合外部電磁鐵作為磁力來源，再以控制系統控制電磁鐵的電流大小，使其對飛輪產生電磁制動與磁滯制動，最後以控制電路及控制程式的最佳化設計，達到高準確性與高性能的制動控制系統。最後本文以實驗的結果數據，與舊有系統比較，扭力增加了39%，功率增加了49%，證實所提出的新型阻尼系統確實可行並且有較高的性能。

Nowadays, the population concentrates in urban area. Considering the time spending in job and workout space limitation, the home use fitness equipment becomes the main stream in modern society. Moreover, energy shortage is the inevitable problem worldwide causing the needs for research and development on self-power generation system with damping driver system more demanding. In response to energy economical concerns, this study focuses on the design and control of self-generator with damping driver system and uses fitness bicycle which is mainly construed with a power generation system, damping system and control system as the target example. This study can divided into three major parts: first, this study introduces the related theories and materials and put the emphasis on the researching of how to improve the efficiency and reduce the noise in the power generation system. Second, the damping driver system will be detailed: Damping system is mainly used in the generator rotor flywheel as a guide magnet and works with external magnetic sources. The control system is to control the current amplitude of the electromagnet and makes flywheel to generate electromagnetic brake hysteresis. Then with the improved design of control program and circuits this study outputs a better brake control system with high accuracy and maximum performance. Finally, comparing the traditional system with this study, the new damping driver system generates 39% more torque and 49% more power outputs. Therefore, this study can testify that the new damping driver system is applicable and with better performance.
