Abstract:

针对具有双通道结构的无刷直流电动机(BLDCM,BrushlessDCMotor)容错系统的高可靠性要求和大范围调速特点,在不增加额外设备的条件下,通过分析两个通道中功率电路直流母线电流波形的特点,提出一种采用归一化快速傅里叶变换(FFT,FastFourierTransform)方法提取频率特征,再结合基于规则的专家系统进行故障检测与识别的方法,并通过实际电动机系统的试验验证了方法的正确性.试验结果表明规一化FFT方法可以消除不同转速和不同负载对判断结果的影响;专家系统中阈值的选取可以有效避免实际应用中出现的噪声等因素的影响.算法复杂度低,可靠性高,易于应用,具有很强的实际操作性.
