高性能战斗机机动动作优化控制研究

应用轨迹优化方法研究了高性能战斗机机动动作的最优控制问题。采用质点运动方程，以多层神经网络完成气动系数拟合，编写了基于最大值原理的优化程序，给出了优化结果，并据此对过失速机动的使用和控制进行了初步分析，结果表明，对特定的始末端状态，过失速机动能力能够缩短机动时间，但是进入过失速的深度与收音机推重比有关。

The Research of Optimal Control for High Performance Aircraft

Optimal control of tactical maneuver for a high-performance aircraft is investigated in flight trajectory. A point mass equation is adopted. The aerodynamic coefficients are calculated via a muti-layer neural network. Two optimal trajectories are obtained, according which the utilization and control of post-stall-maneuvers are analysed. It shows that the capability of post-stall-maneuver results in reduction of the maneuvering time, but the depth with which the trajectory falls Into the post-stall zone is related to the ratio of T/W.
