Simulation Studies on Servo System of Vehicle Satellite Communication in Motion Based on Simulink

在分析“动中通”伺服系统关键技术即天线稳定与波束跟踪的基础上,引入了实际行车时可能会遇到的阴影问题。给出了一种把天线稳定和波束跟踪相结合的方法,建立了基于Matlab/Simulink的仿真模型,进行了“动中通”伺服系统的仿真研究,并给出了仿真结果。仿真结果表明该方法不仅具有有效性,而且对于误差的修正时间也比较短,还能克服阴影带来的问题,对“动中通”伺服系统的研究设计具有实际意义。

The shadow problems which happen in the actual steering vehicle environment were introduced after a prior discussion of the key technology antenna stabilization and beam tracking. A method was proposed which inosculates the antenna stabilization and beam tracking, and the results of simulation studies on servo system of vehicle satellite communication in motion based on the Matlab/Simulink model were proposed. The simulation results show not only the effectiveness of the method, but also the time which used for amending the pointing error is very short, and the shadow problems are avoided. It is aimed to be beneficial for studies and designs of servo system of vehicle satellite communication in motion.
