Problems solved by technology
But this kind of levitation is only formed by the strong repulsive force formed by the permanent magnet and the magnetic track, and the result is that the deviation between the levitation height data of each levitation point in the permanent maglev train is too large
And because the permanent magnet adjustment of the permanent magnetic levitation train belongs to an open-loop control system, it is impossible to effectively feedback and correct the problems such as the large difference between the levitation height data of each levitation point.
This not only seriously affects the riding experience of passengers, but also seriously affects the working performance of the permanent magnetic levitation train

Embodiment Construction
[0057] The present invention will be further described below with reference to the accompanying drawings. It should be noted that this embodiment is based on the technical solution, and provides detailed implementation and specific operating procedures, but the scope of protection of the present invention is not limited to this Examples.
[0058] The track of the permanent magnet suspension maglev train is located above the train, and the pillars supporting the track are made of steel and concrete. The permanent magnet module installed on the bogie of the permanent magnet suspension maglev train forms a strong repulsive force with the magnetic rails installed on both sides of the track, thereby realizing the suspension of the permanent magnet maglev train. In order to keep each suspension point in the permanent magnet suspension maglev train at an ideal suspension height, this embodiment provides a suspension height stability control system and method based on a mixture of perman...

The invention discloses levitation altitude stable control method and a levitation altitude stable control system based on mixing of a permanent magnet and an electromagnet. By a control algorithm based on magnetic flux-current joint inner loop feedback, a problem of greater altitude deviation among levitation points caused by permanent magnet levitation can be solved, and thus, passenger experience can be improved and normal work performance of a permanent magnet magnetically levitated train can be guaranteed.
Description
Technical field [0001] The invention relates to the technical field of magnetic levitation rail transportation, in particular to a levitation height stability control method and system based on permanent magnet and electromagnetic mixing. Background technique [0002] The new permanent magnet maglev rail transit system is a green, safe and intelligent new mode of transportation with the advantages of small footprint, low noise, no friction, no pollution, and easy disassembly. It is an ideal solution to solve the problem of urban traffic congestion and the "last mile" of public transportation. It is especially suitable for the development of public transportation and urban landscape in small and medium-sized cities with beautiful environment, undulating terrain and ecological type. It is a "featured town" transportation system. Preferred. [0003] The track of the permanent magnet suspension maglev train is located above the train, and the pillars supporting the track are made of s...
