Optimization of the HTSC-PM Interaction in Magnetic Bearings by a Multiobjective Design
The paper deals with the shape design of the excitation system of a high-temperature-superconductor (HTSC) magnetic bearing by means of a procedure of multiobjective design. As a result of the proposed method, a set of optimal geometries of the basic excitation structure was extracted from all possible solutions in the objective space. Finally, the sensitivity of the levitation force acting on the HTSC with respect to geometry fluctuations was estimated; this way, the robustness of optimal solutions can be controlled.
