    Abstract: 本論文主要為應用在永久磁鐵同步馬達的無感測器技術開發。永久同步磁鐵馬達分為表面貼磁式和凸極式,因為馬達極性的關係,兩者所使用的無感測器控制技術不同,本文主要是針對表面貼磁式的永久磁鐵同步馬達進行開發。在低速方面,我們應用低頻注入法來做為無感測器控制技術,其優點為不需增加額外硬體設備且可以應用在表面貼磁式馬達,缺點為會有暫態抖動以及由於隨著速度命令增大,反電動勢亦逐漸變大,導致低頻注入法模塊計算錯誤的原因,導致低頻注入法無法應用在高速度命令的情況。在高速度命令使用方面,我們應用參考模型適應法,它是一種自適應性的無感測器控制技術,在中、高速度命令下可以有很好的速度響應結果。而在低頻注入法、參考模型法兩種無感測器技術切換方面,我們藉由調整其中的控制參數來改善兩者的可控制速度命令範圍、速度響應,藉以減少切換兩個無感測器技術時所造成的速度不穩、抖動等情形。在模擬方面,我們使用MATLAB Simulink來驗證永久同步磁鐵速度閉迴路控制、低頻注入法以及參考模型法的結果;實驗方面,則是使用德州儀器TMS320F28379晶片來實現。
    This thesis mainly builds up the permanent magnet synchronous motor sensorless vector control technology. The permanent magnet synchronous motor can be divided into two types: surface-mounted and interior-mounted. Because of the saliency of motor, we have to choose different sensorless control technology for different types of motors. In this thesis, surface-mounted permanent magnet synchronous motor is used for DSP controlled target.In low speed command situation, we utilize low-frequency signal injection (LFSI) method for surface-mounted permanent magnet synchronous motor to perform sensorless control. Because of the back EMF of the motor, this method can only be used in low speed command situation. In high speed command situation, we use model reference adaptive control system (MRAS), which is self-adaptive sensorless control technology and it performs well in high speed command situation.For the stability when changing sensorless control technology for different speed commands, we adjust the control parameters to improve the dynamic response.We use MATLAB Simulink to identify the result, and use TMS320F28379 digital signal processor (DSP) motion control card to carry out the sensorless motor control.
