Strategies of Calculating and Applying the Time Delay to Control Spin-Stabilized Satellites Synchronously

自旋稳定卫星的动力学特征决定了对其控制时必须采用同步控制方式。同步控制要求地面发送的控制命令必须在卫星旋转到特定相位时准确到达卫星。从同步控制的原理出发 ,讨论了基准的生成方法 ,分析了各时延量之间的关系 ,提出了地面实施同步控制自旋稳定卫星时延量的计算模型和应用策略 。

Because of the dynamics characteristics of the spin stabilized satellites, the synchronous control mode is used to control this kind of satellites. In order to execute the synchronous control, the control commands transmitted by ground equipment should reach the satellite at the specified phase precisely. In this paper, according to the principle of synchronous control, the methods of reference generation are discussed, the relations among all dinds of time delay are analyzed and the calculation models and application strategies of the time delay, which are used in the ground euipment to control spin stablilzed satellites, are presented. The satellite synchronous control can be implemented by use of these methods, models and strategies.
