本文研究具有太阳帆板的挠性空间飞行器的动力学与控制问题。对于用偏微分方程或有限元法建立的数学模型,通过求取系统的特征值和模态增益,给出其传递函数,然后设计了具有比例—微分—积分形式的控制器,并进行了稳定性分析。初步探讨了高阶数字模型的降阶问题。最后,应用最优化方法申的Powell方法,对控制器参数进行了最优化设计,并给出了一个计算实例。从而得到一些有益的结论。 This paper studies the dynamics and control of flexible spacecraft with solar panels. For the mathematical model established by partial differential equation or finite element method, the transfer function is given by calculating the eigenvalue and modal gain of the system, and then the controller with proportional-differential-integral form is designed and stabilized Sexual analysis. The problem of reduced order of high-order digital model is discussed preliminarily. Finally, by applying the Powell method in the optimization method, the controller parameters are optimized and a calculation example is given. In order to get some useful conclusions.
