摘要
针对融合风场信息的航空器战略航迹规划问题,将风参数视为满足内蕴假设的区域化变量,利用风场预报信息,采用地统计学中的克里格插值法对特定航路和位置点进行插值,获得了线性无基台、线性有基台及球形3类半变异模型。为了拟合半变异模型中的未知参数,通过基于进化规划的函数模型方法进行参数估计,结合Delaunay三角剖分算法和半变异模型中的变程信息对航空器10个爬升阶段中的10个待估点的风值进行了估计,并给出了方差值。
Aimed at the aircraft strategic trajectory planning problem integrating wind field information,the wind parameter are considered to satisfy the assumptions of intrinsic hypothesis?the geo-statistics Kriging interpolation method is proposed to interpolate specific route by the wind field forecast information?three types of semi-variation models are obtained,such as linear model without base,linear model with base and spherical model.In order to fit the unknown parameters in the semi-variation model,the parameters are estimated by the function model method based on evolutionary programming,the wind values of the 10 points in the 10 climbing stages for the aircraft are estimated through the variation information in the Delaunay triangulation algorithm and semi-variation model,and the variance values is given.
