Research on Redundancy and Fault-Tolerant Control Technology of Levitation Join-Structure in High Speed Maglev Train

摘要

The phenomenon occasionally occurs during the running of the high-speed maglev train that the suspension control unit fail to work. However, whether the suspension system is normal is directly related to the safety of the train. Therefore, the particular levitation join-structure is adopted in the high speed maglev train. This study is conducted to obtain redundancy and fault-tolerant control technology of levitation join-structure. The mathematical model of levitation join-structure is established and the suspension controllers are designed, so as to solve the failure problem of one suspension control unit and improve the reliability of the entire suspension system
