Modeling and Controller Design of Suspension System of Maglev Train

Part of the Springer Tracts in Mechanical Engineering book series (STME)


The electromagnetic suspension-type (also known as attraction type) Maglev technology is one of the mature track transit technologies at present. By virtue of this technology, both Japan’s low-speed Maglev Nagoya Linimo and China’s high-speed Maglev Shanghai Pudong Airport Line succeed in realizing the commercial operation of Maglev traffic line. The electromagnet of electromagnetic suspension-type train is installed under the track. The suspension force is produced by mutual attraction of the electromagnet and the ferromagnetic component on the track. In order to keep stable suspension of the vehicle, the size of electromagnetic force is adjusted by controlling the field current of electromagnet. The electromagnetic force is equal to the train body’s gravity under a certain suspension gap to keep stable suspension of the vehicle. When the electromagnetic suspension-type train cannot realize self-steadiness in the direction of suspension, a closed-loop automatic control system is required [1]. The suspension control system, whose performance can directly affect the stability and safety of train’s running, is regarded as one of the emphases of study with regard to Maglev train. The researches in this chapter mainly include building the system model and designing the suspension controller algorithm and the filtering algorithm.
