摘要：
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. © 2019, Electrical Technology Press Co.
