Design of Automatic Carrier Landing System Based on Prediction and Tracking

由海浪引起的舰船运动严重威胁和影响舰载直升机的着舰安全与着舰精度,针对此问题,提出一种基于预报-跟踪的直升机自动着舰控制律设计方法;首先建立舰船运动模型;然后采用AR自回归模型对舰船运动进行实时预报;再根据频域校正原理设计超前补偿网络,将预报信息补偿至自动着舰系统,进一步减小跟踪延迟;仿真结果表明,该方法能够有效地抑制超调并消除延迟,实现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。

Ship motion caused by ocean wave seriously threatened the safety and the accuracy of helicopter landing. To solve this ques- tion, this paper designs the automatic carrier landing system based on prediction and tracking. First, mathematical model of ship motion is es- tablished; Secondly, estimate the ship motion by AR model. Then designing a leading compensation network according to frequency domain correction in order to reduce tracking delay further. Simulation shows that making the helicopter tracking the deck＇ s heave through estima- tion and compensation increase the accuracy and safety of helicopter landing.
