Maglev Vehicle/Guideway Interaction Model Considering Air gap Optimal Control

This paper presents an integrated model incorporating maglev vehicle/ guideway interaction and proceeds to design an optimal control scheme for the air gap adjustment as an important factor. Firstly, the motion dynamic model of a maglev including a 6 DOF vehicle and the roughness model of guideway is established in the state space. The roughness is assumed to be a non-white stationary random process in the spatial domain. Then, the optimal controller is designed. Finally, the coupled model is simulated via MATLAB software and as a case study German Transrapid08 high speed maglev is considered. The simulation results are very promising.
