【摘要】：從上個世紀(jì)中葉開始，具有永久磁性的材料被應(yīng)用到電機的制造中；高磁能積永磁體的出現(xiàn)，代替了傳統(tǒng)的電勵磁磁極，這大大減小了電機的體積。隨后，功率變換器件和整流器件的出現(xiàn)，更加促進了永磁同步電機的發(fā)展。近年來，永磁同步電機在很多高性能，高效率的驅(qū)動控制領(lǐng)域都得到了廣泛的應(yīng)用。 本文首先在廣泛閱讀相關(guān)文獻資料的基礎(chǔ)上，對永磁同步電機的結(jié)構(gòu)、設(shè)計及應(yīng)用領(lǐng)域進行了綜述。 然后，重點分析了永磁同步電機的數(shù)學(xué)模型，包括DQ軸的磁鏈公式；三相靜止坐標(biāo)系與兩相旋轉(zhuǎn)坐標(biāo)系的互相變換；空間矢量調(diào)制（SVPWM）的內(nèi)容；電流和轉(zhuǎn)速控制PI調(diào)節(jié)器的設(shè)計；反電動勢法觀測器的基本原理；高頻注入法計算電機的速度和角度；逆變器的相關(guān)理論；弱磁調(diào)速的原理等。并重點介紹了反電動勢法和高頻注入法在電機控制中的應(yīng)用，以及二者各自對應(yīng)的電機驅(qū)動調(diào)速范圍。 接下來介紹了Matlab在電機控制領(lǐng)域的應(yīng)用；Matlab作為一款功能強大的計算分析軟件，在電機控制中是一個非常得力的助手；不僅可以用來仿真分析，更重要的是能生成C語言代碼，直接與單片機進行交互，省去了編寫大量代碼的麻煩，十分人性化。 最后，給出了對永磁同步電機進行一系列調(diào)試的過程中的仿真及實驗結(jié)果；將高頻注入法與反電動勢法相結(jié)合可以實現(xiàn)更加良好的電機控制，，實驗結(jié)果也證明了這兩種方法的可行性。
[Abstract]:Since the middle of the last century, materials with permanent magnetic properties have been used in the manufacture of electric motors; the appearance of permanent magnets with high magnetic energy products has replaced the traditional electroexcitation poles, which greatly reduced the volume of the motors. The emergence of power conversion devices and rectifiers has promoted the development of PMSM. In recent years, PMSM has been widely used in many high performance and high efficiency drive and control fields. In this paper, the structure, design and application of permanent magnet synchronous motor (PMSM) are reviewed on the basis of extensive reading of related literature. Then, the mathematical model of permanent magnet synchronous motor (PMSM) is analyzed, including the flux linkage formula of DQ axis, the transformation between three-phase stationary coordinate system and two-phase rotating coordinate system, the space vector modulation (SVPWM). Design of Pi regulator for current and rotational speed control, basic principle of backEMF observer, calculation of speed and angle of motor by high frequency injection method, related theory of inverter; The application of backEMF method and high frequency injection method in motor control and their respective range of motor drive speed regulation are introduced. Then it introduces the application of Matlab in motor control field. As a powerful calculation and analysis software, Matlab is a very powerful assistant in motor control, which can not only be used for simulation analysis, but also can generate C language code. Direct interaction with the single-chip computer, save a lot of code trouble, very humanized. Finally, the simulation and experimental results of a series of debugging of PMSM are given, and the better control of PMSM can be realized by combining the high frequency injection method with the backEMF method. The experimental results also prove the feasibility of the two methods.
