Realizing the fault diagnostic system in maglev suspension train system (MSTS) based on fuzzy comprehensive evaluation method

Since maglev train system is a large system, it is difficult to diagnose the fault to the whole train extent by traditional method of fault diagnosing. The fuzzy comprehensive evaluation method is usually applied to most large systems, which can consider many factors of a large system. Firstly the principle of fuzzy comprehensive evaluation method is introduced, then concerned about the feature of programme logical controller (PLC), it is applied to the fault diagnostic system of MSTS. In the end the data of the experiment is analyzed and this method is proved to be proper in fault diagnostic system of MSTS.
