A model attitude and position control system for large-gap magnetic suspension system using a CCD sensor is studied in this paper. In previous work, a position and attitude sensing method was proposed using a CCD sensor to generate digital data outputs. Based on this achievement, a control system design using a nonlinear feedback technique for magnetic suspended model position and attitude control is applied. The studied system accomplishes a control of the suspended model under different position and attitude in a test fixture. To overcome the fast real time requirement in the control, ROM mapping technique and necessary improvements in circuit design will be discussed. The control law based on system dynamics is formulated, and its implementations with hardware design to the desired output are demonstrated. It results an important improvement of model control in a magnetic suspension wind tunnel application
