The Fault Diagnostic System of Maglev Train Based on Fuzzy Comprehensive Evaluation

The principle of fuzzy comprehensive evaluation method is presented in this paper. Taking maglev train of type CMS-3 as the research object, a model of fault diagnostic system based on fuzzy comprehensive evaluation method is built up on programmable logical controller hardware. Reasonable conclusion drawn by such model is analyzed. Experiments show that the fault diagnostic system in train runs successfully, and can evaluate system fault effectively.
