摘要
本文提出一种基于舰船运动预测的无人机航向指令修正方法,以实时估算舰船所遭遇海浪的幅值与频率,在线预计舰船运动为基础,预测着舰时的舰船状态信息,并利用这些信息生成无人机的航向与航迹角修正指令,以使着舰时无人机与理想着舰点之间的偏差最小。最后利用该方法给出了典型舰船动态特性的高精度仿真结果。
An heading instruction correction method for UAV was presented, referred to as the carrier motion prediction. The system was based on real-time estimation of magnitudes and frequencies of waves, and on-line prediction of the carrier motion. This prediction generated information regarding the carrier states at touchdown, this information was in turn used to generate corrections in the UAVs heading and path angle commands to achieve minimum dispersion around the desired touchdown point and heading. At last, a high-fidelity simulation results of typical carrier dynamics were presented.
