摘　　要：目前,国内大多数卫星通信业务是以固定站卫星通信为主,无法实现在运动中通信。因而,基于卫星通信的运动中通信设备-"车载动中通"系统应运而生。文章研究了两轴捷联式车载移动卫星通信地球站,可实现在运动中实时卫星通信。车载"动中通"伺服控制系统主要研究系统硬件结构、算法设计和系统建模与仿真。由于车辆行驶速度、路况的高度不确定性,车载"动中通"伺服系统采用模糊PID控制,对星策略采用圆锥扫描算法。系统仿真采用MATLAB中Simulink模块完成,仿真结果表明,车载"动中通"伺服系统输入与输出的稳态误差很小,动态性能良好。At present,most of the domestic satellite communications business is mainly in the fixed satellite communication,unable to realize communication in motion. Therefore,based on satellite communication in motion communication equipment-＂communication in moving＂system came into being. This paper researches the mobile satellite communication earth station with two axis strap down,the system can real-time communicate with others in motion through satellite. The research of vehicle＂SOTM＂servo control system includes hardware structure,algorithm design and system modeling and simulation. Due to the high uncertainties of vehicle speed and road conditions,the system uses Fuzzy-PID algorithm and the algorithm of conical scan for star policy. System simulation uses Simulink module of MATLAB. The simulation results show that the system input and output steady-state error is small,and has good dynamic performance.
