摘要 为了获得较高精度的永磁同步电机转子位置,提出一种基于开关型霍尔位置传感器的新型转子位置观测算法。当电机低速运行时,采用改进的一阶加速度算法,引入转速与交轴电流估算转子位置;当电机中高速运行时,利用霍尔位置传感器输出的转子位置信号对滑模观测器算法估算的转子位置数值进行分段线性校正,结合改进的一阶加速度算法进行加权平均处理,得到估算的转速和转子位置。实验结果表明,新型观测算法可减小一阶加速度算法滞后性与霍尔传感器安装误差带来的影响,能在宽速度范围内精确地估算电机转子位置,实现永磁同步电机矢量控制系统的高性能控制。

Abstract:In order to obtain a higher precision rotor position of permanent magnet synchronous motor, a new rotor position estimation algorithm is proposed based on low-cost switching Hall position sensor. When the motor runs at low speed, the improved first-order acceleration algorithm is used to introduce the quadrature-axis current to estimate the rotor acceleration and the rotor position. When the motor runs at medium or high speed, the rotor position output by the Hall position sensor is used to perform the piecewise linear correction on the rotor position estimated by the improved sliding mode observer method. Then the linear weighting method is used to obtain the estimated rotor position and rotor angular velocity by the improved first-order acceleration algorithm and the improved sliding mode observer method. The experimental results show that the new estimation algorithm can reduce the influence of the hysteresis of the first-order acceleration algorithm and the installation error of the Hall position sensor. It can also accurately estimate the rotor position of the motor in a wide speed range and achieve high-performance control of the vector control system of the permanent magnet synchronous motor.
