歸類於角度感測裝置之磁阻式解角器，雖在解角精度面相上不及光學編碼器與磁性編碼器，因在惡劣工作環境下有極佳可靠之性能，且具有體積小、結構簡單及製造成本低等優點，在工業應用上有不可取替之地位，常被運用於軍事、航太及交通運輸等嚴苛環境。近年之研究重點是專注於提升磁阻式解角器之解角精度，以增加此解角器之應用領域。
本論文針對多極轉子之磁阻式解角器之結構與解碼方法等相關問題進行深入研究。先採用電腦輔助工程軟體建立磁阻式解角器分析模型，借助有限元素數值程式進行設計參數之優化，針對解角器輸出電壓波形之諧波分量與畸變率，完善不同尺寸磁阻式解角器之設計優化法則，達成提高解角器解角精度之目的，期望提供此型產品之研發參考依據。
在訊號解調方法上，本論文針對解角器輸出訊號，研究訊號解調與解算之基本原理，設計解算電路來解調訊號波形，並採用角度追蹤迴路法與反正切函數運算法分別解出轉子角度與轉速訊號，並比較其優缺點。實驗驗證過程則架設解角器實驗平台，採用商用馬達驅動系統與軸角數位轉換晶片，進行實驗量測與解析，進行實驗驗證數據之分析與比較。

Variable reluctance (VR) type resolver, classified as rational angle detectors, have excellent performance in harsh operational environment and advantages in compact size, simple structure, and low manufacture costs, though they are inferior in accuracy to the optical or magnetic encoders. Therefore, they are irreplaceable in many militaries, aerospace, and transportation applications. Recently, researches have been focusing on improvement of the resolution of VR resolver so that the field of application can be widened.
This thesis is devoted for investigation in the structure and decoding analysis of the multi-pole VR resolver. First, a commercial CAE software package is adopted for establish the simulation models. The design optimization of VR resolver is based on the harmonic components and total distortions of output voltage waveform, to improve the so that the decoding accuracy can be improved.
Then, the principle of demodulation for decoding the output signals is implemented for signal demodulation. And the servo-tracking loop method and arctangent algorithm is used to resolve the speed and angle of rotor for comparisons. Finally, experimental verifications on a two-pole resolver driven by a stepping motor drive system are conducted with successful measurements compared with the simulation results.
