## Matlab磁悬浮列车电磁系统模型的研究

Magnetic Levitation Control System
Abstract：With the rail, shipping, aviation and other public services the rapid development of maglev technology industry came into being. Maglev technology in environmental protection, speed, etc. Compared with other existing land transport has a clear advantage, with the traditional wheel-rail transportation systems, non-contact magnetic levitation train by the electromagnetic force rather than mechanical force to achieve support, traction, acceleration and braking functions. Because almost no mechanical contact, the train can run smaller noise, but was as high as 500 kilometers per hour. Therefore maglev technology has great significance.
This article will focus on magnetic levitation technology suspension system control technology for further research and discussion, the use of Matlab software maglev suspension gap no static error control systems for simulation studies, based on the principle suspended suspension control simulation system design, and system debugging and waveform analysis and obtain the desired results. 源自L六W维L论W文W网).加7位QQ3249.114 www.lwfree.cn
