摘要
提出了一种基于三自由度扰动模型的测量船光电测量设备抗船摇扰动系统。利用坐标轴旋转的方法将目标的引导数据从大地坐标系转化为甲板坐标系,利用最小二乘法对测量船的姿态角数据进行处理获得测量船的船摇数据,建立了包括横摇、纵摇和艏摇在内的三自由度位置扰动模型和速度扰动模型,并利用前馈控制实现对船摇扰动的补偿。通过仿真得到了与理论分析一致的结果,证明基于三自由度扰动模型的前馈系统能有效提高光电测量设备的跟踪和捕获精度。
An anti-jamming system based on three degree of freedom is applied in measurement ship＇s opto-electronic measure equipment. ＂Ihrget＇s information is transformed from geodetic coordinate system to deck coordinate system using coordinate axis drcumrotation. Measurement ship＇ datum is analyzed to get ship＇s roll, pitch and yaw velocity by least square method. Three degree, of freedom including roll, pitch and yaw is built, and feed-forward is adapted to isolate the influence of ship＇s swing to measure equipment. Computer simulation was implemented and is got the same results that coincide with theoretical analysis, and proved that the feed-forward system based on three degree of freedom can raise measure equipment accuracy.
