摘要
反作用飞轮是卫星姿态控制系统的重要执行元件，速率模式是反作用飞轮一种工作模式，提高飞轮速率模式控制系统的性能对卫星姿态控制系统具有重要意义。详细讨论了反作用飞轮系统的数学模型，在此基础上实现了反作用飞轮速率模式控制系统设计。实验飞轮运行结果表明，设计的反作用飞轮速率模式控制系统能够抑制飞轮内部干扰和噪声，精确复现速率指令。灵敏度分析证明飞轮系统具有较好的鲁棒性。
Reaction wheel is an important executive component of satellite attitude control system, while speed mode is one running mode of reaction wheel. The improvement of speed mode control system of reaction wheel is spurred by high performance satellite attitude control system. In this paper, based on the establishment and analysis of mathematical model of reaction wheel system, a speed mode control system for reaction wheel is designed. Applications indicate that disturbance and noise were counteracted by the designed reaction wheel system and the wheel followed speed command with high accuracy. The robustness of reaction wheel system is demonstrated through the simulation results.
