摘要
提出了一种便于识别的故障特征信息提取方法,即建立各故障状态的模式子空间,在此基础上实现对故障尤其是多类故障的分类识别。通过对内燃机气门故障的实例诊断考核,表明该方法的有效性。
A method which is practical for extraction and recognition of fault characte-ristic is introdnced. The realization of the diagnosis of multiple kind of fault is based onthe subspaces of the fanlt states.The value of the method has been showed in the faultdiagnosis of engine.
