| 摘 要： | 针对飞行控制系统控制器参数优化问题,提出了一种基于反馈和共享机制的改进进化策略。将各代当前最优搜索结果和共享度信息反馈到变异步长的更新公式中,达到提高算法全局搜索能力和搜索精度的目的。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之中,仿真结果表明,该优化策略能够快速有效地整定飞行控制系统参数。

| Abstract: | For the optimization of flight control system(FCS) parameters,an adaptive evolutionary strategy(ES) based on the feedback and sharing mechanism(ESBFSM) is proposed,in which the information of every generation's current optimal searching result and sharing degree is fed into the mutating formula.By these measures,the global and the global searching ability are enhanced.The improved ES is applied to the optimization for a kind of lateral FCS's parameter,the result shows that the evolutionary strategy based on... |
