Computer Aided Optimal Recovery from Windshear

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 principles of the computer aided direct optimization of dynamic system are introduced here,and as a real example,the method is applied to the aircraft recovery from low altitude windshear.After using a real engineering windshear model and choosing a proper structure of control function,a satisfactory performance function and its reasonable restrains,the control of aircraft recovery from low altitude windshear is optimized,by the computer researching for the optimal condition directly,systematically and alternatively.Curves of parameters in the flight corresponding to the optimal recovery are obtained,as well as the comparison of the results with those from the un optimized recovery guiding policy.The final results show that the performance of recovery is greatly improved after the optimization.
