摘要

考虑由两个相同的柔性太阳能电池板和一个中心刚体组成的柔性卫星的PDE-ODE模型。在解的能量呈指数衰减为零的意义上证明了卫星模型是指数稳定的。此外，我们构造了两个基于内模型的控制器，一个被动控制器和一个基于观测器的控制器，使得中心刚体的线速度和角速度渐近地收敛于给定的正弦信号。通过数值仿真比较了两种控制器的性能。

Robust controllers for a flexible satellite model

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.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
