Abstract: To enhance the spatial stability of test models in supersonic wind tunnels, this paper proposes a position and attitude control algorithm for magnetic suspension and balance system based on aerodynamic disturbance compensation. The aerodynamic drag characteristics of the test model are obtained through simulation, based on which an axial system dynamic model is established and a nominal controller is designed. To address the estimation of aerodynamic disturbance, a disturbance estimation strategy based on a prior model is proposed. Simulation results indicate that the method can accurately track variations in disturbance forces. Furthermore, an axial suspension control strategy incorporating aerodynamic disturbance compensation is introduced. Simulation results show that during the wind tunnel startup process, the maximum displacement deviation of the model is within 0.0126 m. Experiments conducted on an aerodynamic resistance simulation platform demonstrate that, compared with active disturbance rejection control, the proposed method reduces the maximum position deviation from 0.03 m to 0.013 m and significantly improves steady-state accuracy after convergence. This approach effectively enhances the system's capability to resist aerodynamic disturbance.
