摘　　要：采用可变步长VS-LMS算法对定子电流进行自适应陷波处理,对其进行频谱分析。这种方法既能很好地解决传统LMS算法存在的收敛速度、跟踪能力与稳态误差之间的矛盾,又能提高故障检测的灵敏度。实验结果证明了该方法的有效性。Adaptive Notch Filter using variable step size VS-LMS algorithm deals with the stator current,and then the spectral is analyed. This method can not only settle the contradiction well between the convergence rate, tracke capabilities and the steady-state error in the traditional LMS algorithm, but also can improve the sensitivity of fault detection.The experiment result shows that the method is effective.
