介绍了动态系统的计算机辅助直接优化方法的原理及其在低空风切变改出飞行中的应用。利用较真实的风切变工程化模型,选择适当的控制函数结构、性能准则及其约束条件,通过计算机直接地、系统地和迭代地探寻最优条件,对飞机改出低空风切变控制进行了优化,获得了最佳改出性能的飞行参数曲线,并与没有优化的改出引导策略的结果作了比较。结果表明,通过优化,飞机改出低空风切变的性能获得了明显的改善。
The principle of computer aided direct optimization of dynamic system and its application in low altitude windshear flight modification are introduced. By using a more realistic wind shear engineering model, the appropriate control function structure, performance criterion and constraints are selected. The optimization conditions are directly, systematically and iteratively probed by computer, After optimization, the flight parameters curve with the best performance is obtained and compared with the results of the non-optimized guidance strategy. The results show that, through optimization, the performance of the aircraft rerouting low-level wind shear has been significantly improved.
