摘要
由海浪引起的甲板运动造成理想着舰点的位置变化严重威胁着着舰安全,为了提高舰载机着舰精度且避免与甲板的剧烈碰撞,必须实现舰载机与甲板的同步运动。采用改进的LQR方法设计的自动着舰系统本身存在着超调和相位滞后。利用闭环系统的频域特性,采用甲板运动预报和补偿技术将预报信息补偿至自动着舰系统,能够有效地抑制超调并消除延迟,实现了舰载机对甲板运动的精确跟踪,提高了舰载机着舰的准确性和安全性。
Deck motion caused by ocean wave changed touchdown point position, which seriously threatened the safety of aircraft landing. Aircraft must follow deck motion in order to improve the precision of landing and avoid hard collision between aircraft and deck. The automatic carrier landing system based on improved LQR method can’t avoid overshoot and lag inherently. Employing deck motion prediction and compensation technology with frequency response can accurately compensate for the overshoot and the lag inherent in altitude command control system and increase the accuracy and safety of aircraft landing.
