小生境遗传算法及其在飞行控制系统中的应用

The Niche Genetic Algorithm and Its Application in the Optimization of an Aircraft Flight Control System

针对飞行控制系统控制器参数优化问题,提出了一种基于小生境遗传算法的模型参考优化整定策略,并将此策略应用于某型飞机的横侧向飞行控制系统的参数优化中。仿真结果表明,该优化策略能够有效地整定飞行控制系统的参数,具有收敛速度快、编程简单的优点。

To optimize the parameters of the aircraft＇s flight control system（FCS）, a reference model method based on the niche genetic algorithm（NGA） is proposed in this paper. To test the validity of this method, a simulation on a kind of aircraft＇ s lateral flight control system is made. It is showed that the method can tune the parameters of the FCS, and converge faster, and be programmed simply.
