| Abstract |
A novel non-contacting guidance system for magnetically levitated high speed transportation systems is presented. In order to simplify the mechanical structure of the vehicle and to avoid weakly damped modes particularly with low eigenfrequencies magnet configurations are developed which can be stabilized in two degrees of freedom - translation and rotation - by means of autonamous gap control circuits. Furthermore failure of one control circuit of a magnet does not influence stability and performance of the overall magnet control. This is achieved with magnetically coupled magnets joined longitudinally by the levitation bogies, fail-safe and redundant gap sensors and fail-safe transistor-choppers operating with 100 kHz sampling rate. Tests on a "magnetic wheel" test stand show the advantages of this concept. |
