摘要

提出了用逐线磁通函数估计无刷直流电机转子位置的方法。该方法在较宽的转速范围内具有较好的效率，并且转子位置的估计不受转速和转子频率的影响。采用直接转矩和SWF两种技术设计了无传感器无刷直流电动机驱动。仿真结果表明，基于直接转矩控制的无刷直流电机控制方法优于开关函数控制方法。

Design and smulation of sensorless BLDC motor drive using DTC and SWF

The method of functions of line by line flux for estimating rotor position in sensorless BLDC drive is presented in this paper. This method has appropriate eificiency over a wide range of speed and it estimates the rotor position independent from speed and rotor frequency. Two techniques of DTC and SWF are used to design the sensorless BLDC motor drive. Finally, simulation results show that the DTC based method for controlling sensorless BLDC motors is superior compared to that of the switching function method.
