On both flux and current feedback control technique for maglev suspension system

For maglev systems, current feedback and flux feedback are two common control methods. But there are many respective disadvantages. To reject the deficiencies of the two methods, a suspension control method based on both flux and current feedback was studied in the paper. To be aimed to a magnetic suspension system, the method of measuring the flux signaler was discussed, the hardware structure of control system was designed. Simulation and single electromagnet suspension experiment based on both flux and current feedback was made, that proved its feasibility to engineering.
