基于AR参数的液压阀故障信号检测
Hydraulic valve fault signal detection based on AR parameter
摘要
Abstract
The paper presents the method to adopt least squares support vector machine to detect the overflow valve fault signal, and shows AR modeling by taking normal signal and fault signal during overflow valve vibration and obtains AR parameter of the collected signal based on the model and then adopts these parameters as input for least squares support vector machine to implement fault identification and achieves satisfactory result.关键词
