摘要:

本文研究线性系的强结构能控性。与现有的工作相比,本文研究的结构化系统具有所谓的零/非零/任意结构,这意味着一些条目等于零,一些条目是任意的但非零,其余条目是任意的(零或非零)。我们形式化的模式矩阵,其条目是固定的零,任意非零,或任意。利用模式矩阵的满秩检验建立了强结构能控性的充分必要代数条件。给出了模式矩阵满秩的一个充分必要的图论条件。这个图论条件利用了本文提出的一个新的颜色变化规则。基于这两个结果,我们建立了结构强能控性的一个充分必要的图论条件。此外,我们将我们的结果与文献中存在的结果联系起来,并解释了我们的结果如何推广以前的工作。

英文摘要:

This paper deals with strong structural controllability of linear systems. In contrast to existing work, the structured systems studied in this paper have a so-called zero/nonzero/arbitrary structure, which means that some of the entries are equal to zero, some of the entries are arbitrary but nonzero, and the remaining entries are arbitrary (zero or nonzero). We formalize this in terms of pattern matrices whose entries are either fixed zero, arbitrary nonzero, or arbitrary. We establish necessary and sufficient algebraic conditions for strong structural controllability in terms of full rank tests of certain pattern matrices. We also give a necessary and sufficient graph theoretic condition for the full rank property of a given pattern matrix. This graph theoretic condition makes use of a new color change rule that is introduced in this paper. Based on these two results, we then establish a necessary and sufficient graph theoretic condition for strong structural controllability. Moreover, we relate our results to those that exists in the literature, and explain how our results generalize previous work.
