摘要
为解决小型无人机易受大气紊流干扰、飞行稳定性较差等问题,根据固定翼飞机GJB185-86及C*规范要求,应用鲁棒性较强的LQR理论设计了无人机纵向增稳控制器,以使其飞行品质满足相关规范要求。仿真结果表明,所设计的增稳控制系统不仅提高了无人机飞行的稳定性,还有效改善了其动态响应和鲁棒性。
In order to overcome the defect that unmanned air vehicles（UAVs） are easily disturbed by air current and tend to be unstable,an augmented-stability controller was developed for a certain UAV＇s longitudinal motion based on linear quadratic regulator（LQR） theory according to flight qualities specifications of GJB185-86 and C＊.The simulation results show that the augmented-stability controller not only improves the UAV＇s stability and dynamic characteristics but also enhances the UAV＇s robustness.
