| Abstract: | The vector spectrum and the fuzzy Petri net are discussed,the fault diagnosis method for rotary machinery based on vector spectrum and the fuzzy Petri net is put forward,and the diagnosis Petri net model is established.Engineering practice indicates that the fault diagnosis accuracy based on vector spectrum and the fuzzy Petri net is higher than that based on the information of single channel and the fuzzy Petri net. |
