Abstract
A novel mechanism of space system based on flux pinning is utilized potentially because flux pinning takes a number of advantages, such as no-mechanical connection and the characteristics of passive stability. In this novel structure, a flux pinned interface is generally composed of a high temperature superconductor and a permanent magnet or an electromagnet mounted on a respective module. In addition, a feasible type of flux pinned docking interface is designed with detailed control strategy. The improved image-dipole model is proposed with intention to calculate the flux pinned axial force between two flux pinned modules, so the axial force can be calculated analytically. In case of zero filed-cooling experiment and field-cooling experiment, the improved version of model is in good agreement with the experimental data measured in our simple experimental device. Furthermore, the potential force and damper model for a flux pinned space system is proposed, so the passive stability of the flux pinned space system is validated in sense of Lyapunov stability.
