战斗机飞行航迹操纵优化控制建模仿真

Modeling and Simulation of Fighter Flight Trail Control Optimization

飞行航迹建模是空战机动决策研究的重要内容。传统飞行航迹建模方法把复杂的飞行航迹分解为多个简单航迹段,每个航迹段简化为直线飞行或转弯机动,传统方法不能真实反映战斗机空战机动过程,机动决策时效性差。为了方便而又逼真地生成战斗机的飞行航迹,提出了一种新的航迹操纵优化控制建模方法:按照战斗机空间机动飞行特点,设计了11种通用的基本操纵动作用来模拟战斗机的飞行航迹,以切向过载、法向过载和滚转角为控制量,利用基于飞行员操纵特点的机动控制方法对战斗机实现平飞、水平转弯、俯冲和爬升等机动进行建模。按照上述方法模拟战斗转弯和半筋斗两种典型战术动作的飞行航迹,并通过Matlap对仿真数据与真实数据进行对比分析,仿真结果表明,所设计的飞行航迹操纵优化控制模型符合空战实际。

Modeling of flight trail is very important part in researching on air combat maneuver decision. The tra- ditional flight trail methods that divided complex flight trail into some simple trail segments and divided every trail segment into straight flight and turning flight, cannot reflect the process of fighter maneuver. To create the flight trail quickly and realistically, a new modeling method of flight trail control optimization is put forward according to charac- teristic of fighter space flight, and eleven kinds of basic operation maneuvers are designed to imitate the fighter flight trail. Taking tangential overload, normal overload and roll angle as control parameters, fly - level, turn - level, diving and climbing are modeled based on characteristic of pilot control. The flight trails of chandelle and half wing are crea- ted through this method, and the simulation data and the real data are contrastively analyzed by Matlab, simulation results indicate that the modeling of flight trail control optimization is truthfulness of air combat.
