针对三轴稳定卫星的姿态控制系统,在离散事件仿真平台OMNeT ++的

基础上,建立了一个以星敏感器和陀螺为敏感器,反作用飞轮为执行机构的闭环

控制仿真系统。采用双矢量定姿算法和P ID控制算法,对该卫星在对地定向模

式下的控制精度进行了仿真。仿真结果清晰地反映了星敏感器和反作用飞轮输

出延时对控制精度的影响。整个仿真系统符合面向对象和模块化的程序设计理

念,并实现了仿真程序的重用。-For the three-axis stabilized satellite attitude control system, discrete event simulation platform for OMNeT++ based on the establishment of a star tracker and gyro for the sensor, Reaction Wheel for the implementation of closed-loop control simulation system bodies. Dual-vector attitude determination algorithm and P ID control algorithm, the satellite-to-ground directional mode, the control precision of the simulation. The simulation results clearly reflect the star tracker and reaction flywheel output delay on the control precision effects. Consistent with the simulation system and modular object-oriented programming concepts, and realize the reuse of the simulation program.
