摘要

本論文主要建立以DSP為基礎的表面貼磁式永磁同步馬達無感測器向量控制技術，永磁同步馬達啟動時馬達需要回到初始位置才能順利啟動，為了使馬達可以從任意位置啟動，利用低頻注入法作為馬達的啟動與低速運轉時的控制方法，此方法可以用在表面貼磁式的永磁同步馬達，對馬達參數改變不敏感，在低轉速時效果良好，但此方法只能在低轉速下使用。
中、高轉速則使用參考模型適應性法，此方法可以用於表面貼磁式永磁同步馬達，且自己能夠啟動不需依賴其他方法輔助也不需要增加額外的硬體電路，但低轉速時效果較差，通常操作在中、高轉速下。
本文在低速時使用低頻注入法在轉速提升後切換為參考模型適應性法，達成低速到高速的永磁同步馬達無感測器向量控制，利用MATLAB Simulink驗證低頻注入法與參考模型適應性法的可行性。
實驗方面，使用德州儀器TMS320F28335數位訊號處理作為運動控制卡，並進行無感測器的馬達控制實驗。

This thesis mainly builds up the DSP-based Surface-Mounted permanent magnet synchronous motor sensorless vector control technology, The motor needed to return to a beginning to start the position to start while starting, For the sake of making the motor can from arbitrary position start, Use Low-Frequency Signal Injection as the control method that start and low speed of motor revolve, Low-Frequency Signal Injection could use in the Surface-Mounted PMSM, The motor parameter not sensitive, Effective in the low speed, But this method can use just under the low speed.
Medium and high speed then use Model Reference Adaptive Control System (MRAS), MRAS can be used for the Surface-Mounted PMSM, MRAS can start don't need to depend on the other methods nor need to increase the additional hardware electric circuit, But the low speed effect is bad, Use in Medium and high speed.
This text is in the low speed use Low-Frequency Signal Injection to promote in the speed after convert into MRAS, Reaching the low speed to high-speed of the motor sensorless vector to control, Make use of the feasibility that MATLAB Simulink identifies Low-Frequency Signal Injection and MRAS.
We use TMS320F28335 digital signal processor (DSP) motion control card, and carry out the sensorless motor control.
