The magnetic suspension and balance system (MSBS) suspending the model against high subsonic flow has been successfully developed at Japan Aerospace Exploration Agency (JAXA). In transonic regime, there are difficulties for MSBS to support the model because aerodynamic force acting on the model increases and its fluctuation also increases accordingly. One of JAXA's MSBS for the 10 cm low speed wind tunnel was modified to improve control system response. A 500 Hz control system with image sensors was developed, and the proportional-integral controller was replaced to proportional-integral-differential controller. In addition, to cope with the larger aerodynamic force, more powerful amplifiers were installed and stronger magnets were also installed in the model. The improved MSBS suspended an ogive-cylinder model with diameter of 10 mm and length of 156 mm up to Mach number of 0.6.
