卫星天线的指向控制与可视化仿真

The Pointing Control of Satellite Antenna and Visual Simulation

文中对卫星天线指向控制的可视化仿真问题进行了研究。首先应用动量矩定理建立系统的动力学模型,并采用经典的PID控制,在SIMULINK中进行了数字仿真。然后通过MATLAB接口接收SIMULINK控制模型传人的数据;在Visual C_++ 6.0中应用OPENGL系统函数,调用卫星3DS模型完成整个可视化仿真。

This paper mainly focuses on the visual simulation of the pointing control of satellite antenna.First the dynamics model of the system is built by the theory of momentum torque.Then a digital simulation adopting the classical PID control is built in the environment of SIMULINK.The main program will receive the datas from SIMULIN through interface of MATLAB.In Visual C++ 6.0,some functions of OPENGL will be used to invoke the 3DS model to finish the visual simulation.
