Application of response surface methodology to robust design for racetrack type high temperature superconducting magnet

This paper describes an approach to robust design of the field coil shape for High Temperature Superconducting Motor (HTSM), considering the maximum B⊥ reduction to enhance the robustness. The robust design to reduce the maximum B⊥ should be considered in order to maintain the stability and substantial improvement on the performance of HTSM. The approach is based on the Response Surface Methodology (RSM) and the estimated model is used to minimize the total sensitivity of design variables. A validity of this approach is verified through comparing the robust solution with the normal result obtained by a conventional optimization procedure.
