| 摘 要： | 提出了挠性卫星受控系统特征频率的概念，并对其进行了分析和研究．着重研究了PID控制器参数与受控系统特征频率的关系．仿真结果表明，非约束模态受控频率随Kp或Kd值的增大而趋于卫星的约束模态频率值；刚体受控频率随Kp和Kd的增大按特定规律变化；而Ki对受控系统特征频率影响微小．最后结合仿真算例研究了受控系统特征频率在在轨辨识中的应用，在传统PID控制系统的反馈通道中引入谐振带通滤波器并以在轨辨识结果设置滤波器参数，有效地提高了控制精度．

| Abstract: | A concept of controlled system characteristic frequencies of a kind of flexible satellites is proposed and researched in this paper. The effect of PID controller parameters on controlled characteristic frequencies is specially investigated. Numerical simulation results indicate that,as Kpor Kd increases,the controlled unconstrained modal frequency approximates to the constraint modal frequency of the satellite,and the controlled rigid frequency varies in specific rules. Ki has little impact on controlled ch... |
