| Abstract: | According to the certainty and uncertainty problem of the fault diagnosis of inertial navigation system,the diagnosis method based on fuzzy sets theory has been put forward,The method and function,by which the diagnosis system automatically gains uncertainty evidence and certainty evidence degree of subordination,are given.The certainty evidence and uncertainty evidence can be dealt with unified method and principle,and the practical mathematical models of the two kinds of evidence are established. |
