摘要

切換式磁阻馬達具結構簡單、成本低、散熱佳與效率高等優點，極適合應用於可調速驅動系統。本論文針對四相8/6極切換式磁阻馬達設計驅動系統，並結合單晶片數位訊號處理器建構一全數位變速控制，且利用轉子凸極位置檢測出每轉極少之脈波信號時間長短，作軟體分段除頻倍率調整，估測馬達速度，藉以提高馬達速度估測的精確度。於驅動系統控制器設計，利用積分比例控制法則的優點，適當設計電流及速度控制器，使馬達在系統參數變動及負載干擾情形下，能得到較佳的性能及負載干擾消除能力。

The switched reluctance motor (SRM) has the advantages of simple structure, low manufacturing cost, cool easily and high efficiency. It is suitable for the variable speed control of drive system. A full digital speed control based on DSP single chip is designed for a 4 phases, 8/6 poles SRM drive. Utilizing the rotor salient pole position of SRM to sense pulse signal for each revolution, measuring the pulse signal time and adjusting frequency rate of DSP by software, the motor speed estimation accuracy is improved. An IP controller for current-loop and velocity-loop is employed to reduce the effects of motor and parameter variations, and to provide a good performance even under load torque disturbance.
