基于HLA的卫星姿态控制系统数学仿真

该文针对三轴稳定卫星的姿态控制系统，着重考虑重力、光压、大气、地磁对其姿态的影响，并对这些环境因素的力矩作用效果建模，利用所建模型对卫星具体构形进行计算，形成一个以飞轮作为主动力矩、通过磁力矩卸载的闭环稳定系统。整个系统在符合高层体系结构HLA标准的商业RTI——pRTI下，建立了SOM／FOM模型，实现了控制器、姿态力学和干扰力矩、管理者各联邦成员之间的信息传递以及仿真问的互操作，并促进了仿真资源的重用，最后对卫星姿态角随时问的变化进行了显示。

Mathematical Simulation of Satellite Attitude Control System Based on HLA

The models of attitude control system of three - axis - stabilized satellite and the torques to the system produced by space environment, particularly in terms of gravity, sun radiation, atmosphere and geomagnetism, are addressed in this paper. It also presents the computational methods for the specific satellite structure by using the models , forming a closed loop stabilization system dumped by magnetic torques and with initial torques through flywheels. Information transmission among controller, Mechanics - Environment and manager federates in the total system has been accomplished by the SOM/FOM models under pRTI which is a commercial RTI and accords with the HLA standard, and displays the curve of simulation data.
