Research on Eddy Current Braking Control Strategy of 600 km/h High-Speed Maglev Train

摘要

As an important guarantee for maglev trains in emergency, eddy current braking system and its control strategy are essential for the safety of high-speed maglev trains. In this paper, the principle of eddy current braking and the characteristics of safety braking force of 600 km/h high-speed maglev train are analyzed. An eddy current braking control strategy for ideal braking curve tracking control is proposed according to the target of safety braking control. This strategy uses a fuzzy controller to determine the eddy current braking level and achieves the target of stopping the train in the target parking area through closed-loop tracking control of the actual train position. The effectiveness of this proposed eddy current braking control strategy is verified by the simulation model built by MATLAB.
