Fault Diagnosis and Adaptive Fault-Tolerant Control of High-Speed Train: Safety in High-Speed Train Traction Systems

High-speed train with its reliable, fast and high loading capacities, has attracted more and more attention in the recent years.With the increasing requirements of the speed and safety of the train operation, a lot of efforts has been devoted to the control design for high-speed trains.Similar to the other complex systems, high-speed train formed by the sensors, motors, electrical components, mechanical drives and so on, will have failures with the long time (distance) operation, which could lead to the delay and even stop of the train.Regarded as the heart of the high-speed train, the traction system provides traction power for the entire system.The faults in the traction system may appear in different locations, such as motor, converters, control units, sensors, and so on.These faults can affect the effectiveness of traction force, and result in reduction of speed or may even stop the train.Thus, it is critical to study fault diagnosis and fault-tolerant control problem for high-spee
