摘要

摘要: 针对中小涌浪的扰动，研究了一种基于少量数据的局域预测方法，应用于海面小型漂浮式动载天线跟踪卫星的方位和俯仰伺服控制中.以天线系统的少量位置数据为基础，采用局域预测算法预测天线的位置，计算天线指向将偏离卫星的偏差值，进行天线指向偏离卫星的补偿控制；基于天线位置间相关性，研究了局域预测算法并进行仿真验证；根据天线系统的组成设计了天线方位伺服控制器，并通过matlab仿真和半实物仿真验证了局域预测伺服控制策略的可行性、可靠性和鲁棒性.

Abstract: A local predictive method based on few data is applied in the azimuth and elevation servo control of the small moving antenna floating on sea under disturbances from medium and small surges in the process of automatic tracking satellite.The positions of the antenna are predicted by the local predictive method on the basis of the few data of the antenna positions，the calculation error between the antenna direction and the satellite will be input to the controller to control the antenna to track satellite.The local predictive algorithm is designed and verified by simulation based on the correlation among the antenna positions.The azimuth controller is designed on the basis of the antenna servo system construction and verified by matlab and hardware-in-loop simulation.Experimental results validate its feasibility，reliability and robustness.
