A SUPERCONDUCTING MAGLEV VEHICLE GUIDEWAY SYSTEM WITH PREVIEW CONTROL- PART-I - VEHICLE, GUIDEWAY, AND MAGNET MODELING/

Part I of this paper presents a dynamic model of magnetically-levitate d (maglev) vehicle/guideway interaction. The vehicle employs a superco nducting electromagnetic suspension system with canted magnets to prov ide simultaneous levitation and guidance in the face of guideway irreg ularities and cross-wind gusts. The dynamic simulation model includes a five degree-of-freedom nonlinear vehicle model, a superconducting ma gnet model, and a multi-span flexible guideway model. The formulation accounts for the dynamic loading on the guideway due to time-varying, distributed magnetic forces imposed by the vehicle. The maglev vehicle /guideway model is the basis for designing and testing a proposed prev iew control strategy in Part II of this paper.
