| 摘 要： | 提出了一种改进的永磁同步电机转子初始位置检测方法。首先向永磁同步电机中注入两次线性无关的高频电压矢量得到两次电流响应,计算得到电感矩阵,通过电感间的关系提取转子位置信息,最后通过极性判断确定转子实际位置。该方法较传统的高频电压注入法有精度高、结构简单等优点。仿真结果验证了该方法的有效性。

| Abstract: | An improved method was proposed to detect the initial rotor position for PMSM.Firstly,two groups of linearly independent high-frequency voltage vectors were injected into the PMSM to get two current response.Then,the inductance matrix was obtained by calculation,and the rotor position information was extracted through the relationship between the inductance.At last,the actual position of the rotor was determined by polarity judgment.The method has the advantages of high precision and simple structure.The effectiveness of the method was verified by simulation. |
