| 摘 要： | 对速率模式飞轮姿态控制系统的能控性、稳定性和飞轮组合切换过程进行了研究，揭示了在飞轮组合切换过程中引起卫星姿态抖动的原因，提出了通过对残余角动量进行卸载并将卸载函数同时前馈到系统输入的方法，以保持卫星姿态的稳定度。从理论上证明了可引入残余角动量进行卸载，将卸载函数同时前馈到系统输入，并且不改变原系统的能控性和稳定性。给出了某卫星飞轮切换应用实例，说明了飞轮组合平稳切换方法的有效性。

| Abstract: | The paper deals with controllability, stability and switch process for speed mode momentum wheel assemblies of attitude control system. The cause arousing attitude dithering during switch process for momentum wheel assemblies is analyzed. Keeping attitude stability during switch process for wheel assembly by means of angular momentum unloading and feeding simultaneously unloading function forward to system input is proposed. It does not influent the controllability and stability of the system by introducing unloading remains angular momentum and feeding it forward to input. The effectiveness of the method is demonstrated through the application of a satellite. |
