As part of this article, a method for ensuring the reliability of the operation of complex electrical equipment in transport is presented. The method consists in developing an intelligent diagnosis system for industrial frequency converters that are part of frequency-controlled electric drives. The authors proposed a procedure for obtaining the optimal logical algorithm for diagnosis of this equipment and performed a software implementation of this procedure. The desired algorithm is obtained. It determines the structure of the knowledge base of the expert system for diagnosis of industrial frequency converters. The correctness and efficiency of the expert system, implemented in accordance with the specified structure, is confirmed in practice.
