| 摘 要： | 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PID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。

| Abstract: | This paper aims at the attitude control system of three-axis-stabilized satellite,builds a closed loop control system which includes star sensor,gyro and counteract flywheel based on the discrete event simulation system OMNeT .The double vector attitude determination and PID control algorithm are used to simulate the attitude control precision of the satellite on the face Earth mode.The simulation results clearly reflects the affection of output delay of the star sensor and counteract flywheel to the control precision.The whole simulation system accords with the face object and modularization programme regulation,also achieves the simulation program reusable. |
