A two-level aerodynamic optimization method based on surrogate models is proposed for aerodynamic optimization of high altitude long endurance UAV family configuration design.
针对高空长航时无人机族气动外形优化问题，通过借鉴多学科优化中的二级优化和代理模型方法。
The surrogate-based two-level optimization is developed by use of the surrogate model in the two-level optimization.
在此方法中引进代理模型的概念形成基于代理模型的二级优化方法。
By sequentially adding sampling points both globally and locally in the design space, the accuracy of the surrogate models is gradually improved until reaching the expected level of accuracy.
在建立代理模型时，通过连续成批地在设计空间的全局和局部均加入新样本点，不断提高代理模型的全局拟合精度，直至获得满意的代理模型为止。
