摘要
比较研究了大攻角导弹的经典和现代控制方法的精度和鲁棒性。基于大攻角非线性弹体动力学模型,根据经典三回路控制系统结构和动态逆双时标极点配置方法分别设计了控制器,研究了两种控制方法的指令跟踪精度和抗弹体气动参数摄动的鲁棒性。结果表明,传统控制方法的鲁棒性和快速性与现代方法基本一致,而现代方法则具有更好的稳态精度。
Comparisons on precision and robustness of classic and modern controls for high Angle-ofAttack （AOA） are presented.Based on the nonlinear characteristics of the high AOA missile,two kinds of missile longitudinal autopilot are designed using classical three-loops configuration and dynamic inversion embedded pole placement technique respectively.Study on their command tracking precision and robustness have been conducted.It＇s proved by simulation that classic and modern controls are nearly identical in either rapidity of response or robustness,but modern control can obtain better tracking precision.
