| Abstract: | In this paper,a computer self-learning method for the data base in fault diagnosis system of a rotating machinery is described. During long running,the computer can automatically adjust the data base in diagnosis system, so as to adapt the variatoin of parameter of the machine set that is monitored. Thus the adaptability of the diagnosis system can be greatly strong then.The recursive least square method is used for computer self-learning,and as an example the FUZZY diagnosis system in "MMMD-1" system is introduced to describe the principle and the application of the method. It is shown that the method is stable for any initial value. |
