摘要

为提升试验模型在超声速风洞中的空间位姿稳定性，本文提出一种基于气动力干扰补偿的磁悬挂天平位姿控制算法。通过气动仿真获取试验模型阻力的特性，建立轴向系统动力学模型并设计标称控制器。针对气动力干扰估计问题，提出基于先验模型的扰动估计策略，仿真表明该方法能准确跟踪干扰力的变化。进一步，提出基于气动力干扰补偿的轴向悬挂控制策略，仿真结果显示在风洞起动过程中，模型最大位移偏移量控制在0.0126 m。试验基于气动阻力模拟平台开展，与自抗扰控制对比表明：所提方法将最大位置偏移从0.03 m降至0.013 m，且收敛后稳态精度显著提升。该方法有效增强了系统抵抗气动干扰的能力。

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.
