摘要
为了达到机载动中通天线剖面低、迎风面小、动态响应快的要求,介绍了一种3个天线阵面的动中通天线。该天线的多阵面控制系统采用了速度前馈补偿控制策略、同步控制策略和稳定控制策略,使得3个天线阵相互协调、精确运动以快速对准卫星,实现天线与卫星的实时通信功能。建立了系统的运动控制模型,基于MATLAB对无前馈补偿和有前馈补偿两种方式分别进行了仿真。通过仿真和实际测试表明,引入速度前馈补偿大大提高了动态响应性能,达到了机载动中通天线的静态精度和动态跟踪要求。
To meet the requirements of airborne SOTM （satcom on the move） antenna such as low pro file, small windward side, and fast dynamic response, this paper introduces an airborne SOTM antenna that contains three antenna arrays. The multi - array antenna control system used velocity feed - forward compensation control strategy, synchronization control strategy, and stability control strategy to coordinate the three antenna arrays and align with satellites in an accurate and fast way to realize real -ime communication. Besides, a motion control model of the system was built, and simulations of non - feed - forward and feed - forward compensation were conducted by using MATLAB. The results show that the performanee of dynamic response can be improved by using velocity feed- forward compensation, which meet the requirements of airborne SOTM antenna for static accuracy and dynamic tracking.
