【摘要】 反作用飞轮是卫星姿态控制系统的重要执行元件,提高飞轮系统的性能对卫星姿态控制系统具有重要意义。介绍了反作用飞轮力矩模式反馈补偿控制系统的设计。首先建立了反作用飞轮数学模型,并分析了摩擦力矩干扰和速率测量噪声的特性,在此基础上进行了反馈补偿控制的设计。理论分析证明,应用反馈补偿控制的飞轮系统能够精确复现力矩输出指令。运行结果表明,在复现力矩输出指令精度方面,应用反馈补偿控制的飞轮系统优于电磁力矩控制的飞轮系统。特别在克服过零力矩干扰上,应用反馈补偿控制的飞轮系统具有较高的性能。更多还原

【Abstract】 Reaction wheel is an important executive component of satellite attitude control system,and the improvement of flywheel system is spurred by high performance satellite attitude control system.In this paper,the design of a feedback compensation control system for reaction wheel of torque mode is introduced.Based on the establishment of mathematical model of flywheel and the analysis of disturbance and noise,the feedback compensation control system is designed.It is approved theoretically that the designed system may execute torque output command with great accuracy.A performance comparison of the feedback compensation control system for reaction wheel with the current control system without friction compensation is given to show the advantage of the feedback compensation control system over the later.Applications indicate that the designed flywheel system avoids zero-crossing output torque fluctuation with satisfactory performance.更多还原
