| 摘 要： | 提出了一种改进的基于霍尔元件的永磁同步电机转子位置估计方法。利用牛顿插值法对霍尔元件提供的离散位置点进行曲线拟合,对位置信息进行预测、插值,从而估算出电机转子的实时位置信息。改进后的方法可以消除转子位置估算的阶跃现象,提供稳定可靠的转子位置信息,提高了闭环系统的稳定性。在Plecs仿真平台中对该算法进行了仿真验证,与传统转子位置估算方法进行了对比,仿真结果验证了该方法的有效性。

| Abstract: | An improved rotor position estimation method of permanent magnet synchronous motor (PMSM) using Halleffect sensors was proposed. According to the Newton interpolation method, the curve fitting of discrete locations provided by Hall sensors was made. The realtime position information of the motor rotor was estimated in the algorithm for position fitting and interpolating. This method promised to eliminate the step position of the rotor position estimation and provided stable and reliable rotor position information, so that the stability of the closedloop system was improved. The simulation based on the simulation platform of Plecs was built. Compared with the traditional estimation method of rotor position, the results illustrated the effectiveness of the proposed method. |
