摘　　要：为有效控制空飘气球航迹,提出了一种通过非线性模型降阶处理风场数据,仿真模拟空飘气球航迹的方法。首先基于大量的历史实验数据,建立风场数学模型,对当前时刻与未来一段时间内的风场分布情况进行预测;然后,仿真模拟不同高度层空飘气球的运动情况,并在MATLAB软件中创建图形用户界面,动态展示其运动轨迹曲线。研究表明,空飘气球能够通过主动选择合适的弱风层,实现长时驻空与一定范围内的区域驻留。该方法可促进空飘气球飞行控制技术的发展。In order to control air-floating balloon trajectory effectively,a method is proposed to simulate it by processing wind field data with nonlinear reduced-order model.Firstly,based on a large number of historical experimental data,a mathematical model of wind field is established to predict the current\future wind field distribution.Then,the motion of the air-floating balloon at different altitude levels is simulated,and a graphical user interface is created in MATLAB software to dynamically display its trajectory curve.The research shows that the air-floating balloon can achieve long-term and regional residence in a certain range by actively selecting a suitable weak wind layer.This method can promote the development of air-floating balloon flight control technology.
