基于小波包变换的超声电机堵转检测
摘要
超声电机堵转时对其本身危害很大
对其进行实时检测至关重要。利用小波包变换模极大值原理对电机堵转时的奇异信号进行定位和确定持续时间
通过小波包分解与重构
更好地提取电机堵转时的特征信息。为超声电机的缜密监测、有效控制提供依据
以便采取相应的措施遏制超声电机堵转的发生。
Abstract
Ultrasonic motor stalling is harmful to itself
so it is very important which ultrasonic motor are detected on-line.By using of wavelet package transform module maxima
singularity signal of motor are detected and determined at motor stalling.Through wavelet package resolving and rebuilding
the characteristic information of the ultrasonic motor stalling is collected
the basis for deliberate supervising;effective control of the motor are provided.Correspondent measures are taken to suppress the happening of the motor stalling.
