Modeling of hybrid suspension system of superconducting and electrostatic suspension

Based on a method used to calculate the magnetic field in a thin clearance between superconducting blocks, this paper analyzes the force characteristics of the superconducting passive suspension system. Superconducting magnetic suspension system is an essentially self-stabilization system. At the basis of the existing structure, an electrostatic suspension system is introduced to obtain great suspension stiffness. Then, the corresponding controller is designed and many details about operating conditions are also analyzed. Simulation results show the feasibility of this model. This paper provides a theoretical guidance for the next experiment, and also has reference meaning to the supporting system of accelerometer, gradient meter, and flywheel and so on.
