Tóm tắt

Through the theoretical analysis and experiments on the test, the levitation control system stability of the MAGLEV vehicle on elastic track was investigated. Firstly, taking the single magnet coupled with elastic track as the object, the corresponding mathematical model and the real-time test platform based on dSPACE were founded. Secondly, two kinds of the state feedback controllers were developed based on Kalman filters, and their influences on the stability of the MAGLEV system were investigated, respectively. The research results show that, if the track has no damping, the controller treating the tracks as fixed cannot make the MAGLEV system steady. However a harder track stiffness enables the system, with a certain track damping, to stabilize. The control method considering the track’s flexibility can soundly maintain the system’s stability even if the track has a relatively soft stiffness and no damping effect. The tests on the real-time test platform verified the effectiveness of the latter control method.
