Modeling of the Superconducting Suspension System With Shaping Blocks

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 suspension system. The superconducting suspension system is stable even without feedback control. Linear feedback control is still introduced to improve the suspension stiffness. Then, the corresponding controller is designed, and many details about the 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 the superconducting accelerometer, gradient meters, flywheel, and so on.
