本論文針對健身車結合發電功能之需求，提出一創新動力傳動模組及其輔助動力控制策略，使踩踏者進行不同騎乘行為時，輸出端發電機可維持穩定的轉速，進而達到輸出固定電氣頻率之目的。有別於傳統架構中電力系統調控電氣頻率的方法，藉由本論文所提出的動力傳動模組，便能使發電機直接輸出穩定的電氣頻率，利於後端的電能利用。在此創新的動力傳動模組，以行星齒輪系為主要傳動元件，透過其雙輸入單輸出的傳動結構特性，搭配一組動力輔助馬達實現所設計的穩速控制策略，依據輸入變動踩踏轉速，藉由調控馬達的輔助動力進行速度耦合，使輸出端維持固定轉速。考量真實發電系統中的負載變動影響，本論文採用了全閉環迴路的穩速控制架構，確保輸出響應可達到理想的轉速值，亦因應真實的騎乘情況與控制迴路運行時的安全性，加入動力輔助策略以修正輔助馬達轉速命令。透過所建立的擬真健身車實驗平台，並以輸出端的負載馬達模擬發電系統的動態電氣負載，驗證本論文所提穩速控制架構設計的可行性。

This thesis proposes a new speed regulation control module applied to exercise bike power generation systems which can maintain a required frequency by controlling the generator’s constant rotor speed. In conventional approaches, electricity output generated from a variable speed generator will require an additional power converter to fulfill the grid connection requirements. In this thesis, a new converter-less approach employed between exercise bike and power generator systems is proposed. Moreover, the transmission system incorporated with a planetary gearbox and an electric motor is adopted. Based on its appealing feature of 2-inputs/ 1-output port, the power assist strategy can be realized with an electronically controlled motor. According to speed information measured from manual pedaling and also considering that in reality power systems are always affected by load variations, a full closed-loop position feedback control is designed for ensuring the output speed will remain constant even affected by the electromagnetic torque. Furthermore, four kinds of power assist strategy are employed in the control loop to react to different riding situations so that the system could be operated safely. The feasibility and effectiveness of the proposed method is verified by the experimental results.
