日本宇宙航空研究开发机构已研制出一套60厘米的磁悬浮和平衡系统。包括滚转力矩的模型上的磁力是通过磁悬浮轴承试验段周围10个线圈的电流来控制的。测力标定试验结果表明，测力误差小于1%FS。MSBS的基本控制器是PI和一个双相超前器。新增加的控制器抑制了x轴和y轴运动之间的干扰，并通过增加磁场反馈回路来更快地改善模型的运动。给出了用MSBS模拟飞艇模型的支承干涉、几种轴对称外形的阻力系数以及球阻力和底压的雷诺数依赖关系。
A 60cm Magnetic Suspension and Balance System has been developed at JAXA. Magnetic force on a model including rolling moment is controlled with currents through 10 coils around test section of the MSBS. Force calibration test results show error is almost less than 1% FS. Basic controller of the MSBS is PI and a double phase advancer. Newly added controllers suppress interference between motions in x-axis and around y-axis, and also improve model motion much more rapidly by adding magnetic field feedback loop. Support interference of an airship model, drag coefficients of several axis-symmetric shapes and Reynolds number dependency in sphere drag and base pressure using the MSBS are presented.
