本文提出了一种新的开关磁阻电机无位置传感器控制方法。根据磁链-位置-相电流特性，采用数值方法初步计算转子位置。然后，设计了考虑加速度变化的三阶锁相环，以消除电流采样噪声和数值残差对转子位置估计的影响。提出了一种新的启动顺序。仿真和实验结果表明，所提出的无位置传感器控制方法在位置和速度估计方面都达到了足够的精度。
In this paper, a new position sensorless control method for switched reluctance motor drives is proposed. Rotor position is initially calculated based on the flux linkage-position–phase current characteristics by numerical method. Then, a third-order-phase-locked loop considering the acceleration variation is designed to undermine the impact of current sampling noise and numerical residual error on the estimated rotor position. A new start-up sequence is proposed. Simulation and experimental results show that the proposed position sensorless control method has achieved sufficient accuracy in terms of position and speed estimation.
