摘要
将电影经纬仪三坐标测量数据辩识航弹最佳符合阻力系数曲线描述为一个跟踪最优控制问题,给出了符合阻力系数曲线的参量化描述并将泛函极小问题转化为多变量参数极小问题,给出了具体算法及减少计算量的技术.讨论了弹道方程的初值修正问题.通过某航弹的多枚轰投测试数据处理结果及比较,验证了本文方法和相应软件的可应用性.
In this paper, extracting aerobomb's optimal fitting drag coefficient curve from 3-dimensional theolodite film data is regarded as an optimal tracking control problem. A parameterization description of the fitting drag coefficient curve is given. The functional minimization problem converts into multivariable minimization problem. Detailed algorithm and the technique for computation reduction are also given. Initial state corrections of trajectory equations are discussed. The data reduction results and their comparisons from some aerobomb's bombing testing information indicate that the optimal dynamic fitting method and the relevant software are applicable.
