摘　　要：提出了LMS自适应噪声抵消的方法来实现无刷直流电动机换向位置的检测,改进采用端电压检测确定换向位置的方法,使电机在低速运转下仍有效工作。完成计算机仿真和DSP实现方案。仿真结果表明,自适应噪声抵消法可以有效地运用在反电势检测法中,比传统的检测法简单可靠。This paper puts forward the method of LMS adaptive noise counteraction to detect commutating signals of BLDCM is presented which uses the voltage to detect the communtating position signals thus the moter work effectively in low rotate speed. Then finishing computer simulation and the scheme by using DSP. The results demonstrate that the adaptive noise counteraction method can be used effectively in BEMF detecting. The method provides more simplicity and validity than traditional method.
