降低俯仰气动非线性特性的飞行器总体随控优化方法
摘要：
本发明公开了一种降低俯仰气动非线性特性的飞行器总体随控优化方法，用于解决现有飞行器外形多目标多学科综合优化设计方法控制性能差的技术问题。技术方案是首先建立飞行器总体随控优化目标函数；再确定飞行器总体随控优化约束条件；选取飞行器总体随控优化决策变量；确定飞行器总体随控优化决策变量寻优边界；建立飞行器总体随控优化完整模型；基于遗传算法的飞行器总体随控优化。由于通过建立飞行器总体随控优化目标函数，选取飞行器总体随控优化决策变量，确定飞行器总体随控优化决策变量寻优边界，建立飞行器总体随控优化完整模型，最后采用遗传算法寻优，得到优化总体外形参数。该优化外形下的飞行器俯仰通道的气动非线性得到了有效降低。
