| Abstract: | The practical application of expert system to design of fault diagnosis of chopper circuits, as well as its theoretical basis, is presented. The knowledge base is designed as a multidimensional tree.The diagnosis data are collected through testing and reasoning the objects. Fault positioning is realized by using characteristic vectors.It is much simpler to use fault diagnosis model of function gradation than to use mathematical models based on network theory. |
