| 摘 要： | 针对三轴稳定卫星的姿态控制系统,在离散事件仿真器OMNeT 的基础上,建立了以陀螺、星敏感器为敏感器,以反作用飞轮为执行机构的三轴稳定卫星的闭环控制系统.对于卫星姿态控制系统中控制周期的选取作了初步的分析,最后采用双矢量定姿算法和PID控制算法,设定多种控制周期,对该卫星在对地定向模式下的控制精度进行了仿真,仿真结果清楚的显示了控制周期对姿态控制精度的影响.

| Abstract: | Aimed at the attitude control system of three-axis-stabilized satellite, a closed loop control system simulation platform is built including gyro, star sensor and counteract flywheel, based on the discrete event simulation system OMNeT . And the choice of the control period of the attitude control system is analyzed. The double vector attitude determination and PID control algorithm used to simulate the attitude control precision of the satellite on the face Earth mode at multi-control period, the simulation result clearly displayed that the control period have an effect on the attitude control precision. |
