| 摘 要： | 本文提出了一种将直接转矩控制应用于无刷直流电机的无位置传感器控制方法。需观测无刷直流电机的直流母线电压及定子侧的三相电流，从而估算出电机的磁链、转矩以及位置角，再根据转矩、d-q坐标系上的电流分量以及转子位置信息来选择相应的电压空间矢量，以实现对无刷直流电机的控制。仿真和实验结果表明本文提出的控制方法有效可行。

| Abstract: | A direct torque control for sensorless brushless DC motor is presented in this paper. The control method presented requires observation of the DC bus voltage and the three-phase stator currents of brushless DC motor, and estimate the flux, torque, and rotor position angles of motor. In order to control brushless DC motor, the appropriate voltage space vector is selected according to the torque, current component on d-q axes and rotor position. The simulation and experimental results show that the control method is valid and feasible. |
