论文摘要
我们考虑了一个柔性卫星的PDE模型，该模型由两个相同的柔性太阳能电池板和一个中心刚体组成。我们证明，卫星模型在溶液的能量呈指数为零的意义上是指数稳定的。此外，我们构建了两个基于内部模型的控制器，一个被动控制器和一个基于观察者的控制器，使中心刚体的线性和角速度渐近地收敛到给定的正弦信号。提出了数值模拟，以比较两个控制器的性能。
We consider a PDE-ODE model of a flexible satellite that is composed of two identical flexible solar panels and a center rigid body. We prove that the satellite model is exponentially stable in the sense that the energy of the solutions decays to zero exponentially. In addition, we construct two internal model based controllers, a passive controller and an observer based controller, such that the linear and angular velocities of the center rigid body converge to the given sinusoidal signals asymptotically. A numerical simulation is presented to compare the performances of the two controllers.
