| 摘 要： | 分析无刷直流电机的电磁转矩和起动控制,针对无位置传感器的永磁无刷直流电机的起动控制,提出了具有升频和电流调节控制的无位置传感器BLDCM的起动控制,其中电流调节控制采用两点式比较器控制。该起动控制方法不但有能效控制起动电流大小,而且改善了BLD-CM开环起动性能,提高了系统的可靠性。仿真结果验证了该起动控制方法的有效性。

| Abstract: | The electromagnetic torque and start-up control of brushless DC motors are analyzed.For the start-up control problem,a control method based on increasing frequency and current control is proposed to deal with it,and the current adjustable control applies the two-point comparison device.This method can not only control size of the starting current efficiently but also improve open-loop starting performance of BLDCM,so improve the reliability of the system.The simulation results proves that this method is eff... |
