摘　　要：针对带有大型太阳帆板的挠性空间飞行器动力学特性十分复杂的特点 ,通过合理的假设 ,采用单轴解耦分析姿态控制系统稳定性问题。采用极点配置法 ,按照刚体卫星设计系统PID参数 ,利用根轨迹 ,确定按刚体卫星参数设计的系统能使挠性空间飞行器控制系统具有渐近稳定性的充分条件 ;推导系统参数间的关系式 ,分析挠性空间飞行器主轴姿态控制系统稳定性问题。最后 ,通过仿真验证了系统的性能。Because the dynamics' property of the flexible spacecraft with large solar panels is very complex, decoupling method is adopted to study the stability of the attitude control system for single axis through suitable assumption. The system PID parameters are designed using polar asset according to rigid satellite. Then with root locus method, the sufficient condition is determined that the system designed by rigid satellite parameter ensures the stability of flexible spacecraft control system. The relation among parameters is derived and the stability of single axis flexible spacecraft attitude control system is studied. At last, the system performance is verified by simulation.
