Lateral Force Control Through Armature Currents in Superconducting LSM Maglev Vehicle

The ride comfort or stability of the superconducting maglev vehicle is still the area to be investigated for commercial implementation. This paper proposes a method to get the vehicle guidance forces for a superconducting EDS maglev with LSM propulsion. The author has previously proposed a methodology of analysis using dq0 transformation with space harmonics included, and obtained the exact expression for the propulsion force in terms of q,axis component. It is shown that the d-axis components of the LSM armature currents result in lateral forces, and we show the formulation and design the vehicle motion regulator system, demonstrating the high performance by computer simulations.
