The paper describes an expert system for the power systems steady state diagnosis (PSSD). After the introduction, the second section presents the theoretical background regarding the applying of the model based diagnosis (MBD) to the power systems steady state operation. Basic concepts and the MBD models for the discussed case are given. Within the third section, the PSSD structure and its components...
The paper presents the range and possibilities of using expert systems at diagnostic measurements of insulation systems of power appliances taken by the acoustic emission (AE) method. Multi-parametric descriptors characterizing the AE signals, which can be used in the knowledge base as criteria making the identification of basic partial discharge forms (PDs) possible, have been characterized in detail...
Expert system is widely used in fault diagnosis, but how to obtain knowledge is a bottleneck restricting its development. Data contains rich information about the machine, and acquiring knowledge from it or data mining in other words is considered as an effective way solving this problem. An algorithm based on rough set and genetic algorithm for feature reduction is proposed in this paper. Minimal...
For the problem of fault diagnosis of aircraft fuel system, a new method using CLIPS to build expert system is presented in this paper. By building knowledge base, infer engine and using CB tool, the relevant software environment is set up. Consequently the fault diagnostic system of aircraft fuel system is successfully developed. The emulation results prove that the intelligence of expert system...
