基于遗传算法的航空火力/飞行控制系统研究

Analysis and Simulate an IFFC System by Parallel Genetic Algorithm

分析和仿真了空—地水平轰炸方式下的火力/飞行综合控制(IFFC)系统。文中介绍了将飞机视为空间质点的飞机运动和飞行控制模型,利用轰炸坐标系建立了火控解算模型;运用PID控制建立了基于滚转、俯仰和推力三通道的火飞耦合器模型,最终利用遗传算法对耦合器参数进行优化从而求得最佳解;最后在VC++6.0环境下对系统进行了仿真,分析和验证了遗传算法在参数优化的作用以及在水平轰炸方式下综合控制技术有利于提高系统的工作性能。

In this paper, classical control theory was used to analysis and simulate an integrated fire and flight control （IFFC） system. Fistly,the fundamental of the IFFC system was analysed and a macrocosm system structure was established. Secondly,the arithmetic model of aircraft and the constitution of flight control system were discussed. The algorithm model of fire control calculation was established with bomb＇s reference frame. Then,the ＂fire-fly＂coupling which based on the three channels of the roll, pitch and thrust was established with the PID control. The ＂fire-fly＂coupling was optimized with genetic algorithm. At last, the IFFC system was simulated under the environment of the VC＋ ＋ 6.0. The effect of the genetic algorithm used in optimizing parameter and capability of the system was validated.
