摘要: 本篇論文主要在探讨可变结构控制在非线性系统上的应用。就我们所知,可变结构控制有很多优点,如反应快速、对系统的不确定参数及杂讯不敏感、容易设计等等。另一方面,随着航空及工业界对可靠度的要求增加,有关可靠度控制的研究在这几年也成为一个非常热门的议题。在本论文中,我们结合上述并针对人造卫星提出可变结构可靠度控制。除此之外,针对线性控制系统,我们介绍两种连续的可控性量测,到不可控的距离及特征值的移动能力,而非仅仅是或不是的二元可控性判断。
This thesis investigates Variable Structure Control (VSC) of nonlinear systems, which has many advantages, such as fast response, small sensitivity to system uncertainties and disturbances, easily designed and so on. Also, as a result of the fast growing demands of system reliability in aerospace and industrial process, the research of reliable control is a popular issue in recent years. Here, we integrate both of them and propose reliable VSC control schemes to spacecraft attitude tracking problems. In addition, rather than giving yes or not answer for the controllability of a system, we introduce two controllability measurements, The Distance to Uncontrollable and Mobility of Eigenvalues, which define controllability measure base on continuous rather than binary.
