基于xPC Target的卫星动力学实时仿真

Satellite Dynamical Real-time Simulation Based on xPC Target

为了实现对卫星动力学的实时仿真,采用Matlab/Simulink建立了卫星动力学计算模型,并利用RTW(RealTime Workshop)将计算模型生成xPC Target环境下的目标应用程序,在目标机PC104上运行,实现了对卫星位置、速度、角速度和姿态四元数的实时计算。

To carry out real-time simulation of satellite dynamics, computation model of satellite dynamics based on Matlab/simulink was established, and RTW （Real-Time Workshop）was used to generate target application procedure of computation model in xPC Target. The procedure was run on target computer PC104, and real-time computation of position, velocity, angular velocity as well as attitude quaternion was realized.
