摘要:

本文研究了李群上漂移双线性系统结构能控性和可达性的图解条件。考虑一类具有漂移和受控项的双线性控制系统,它分别在特殊正交群、一般线性群和特殊酉群上演化。零模式规定的漂移和受控动力学相对于一组基本元素在相应的李代数。漂移动态必须遵守刚性零模式,因为漂移取值为具有严格非零系数的基本元素的线性组合;受控动态允许遵循自由零模式,其中受控项的配置中的系数可能为零,这是通过受控基本元素的线性组合实现的。首先,对于特殊正交群或特殊酉群上的双线性系统,证明了零模式与两个无向图或有向图相关联,其连通性和连通分量保证了结构的可控性/可达性.其次,对于特殊酉群上的双线性系统,我们引入了与漂移和受控零模式相关的两个边有色图,并证明了与连通度和特定颜色边数相关的结构可控性条件。

英文摘要:

In this paper, we study graphical conditions for structural controllability and accessibility of drifted bilinear systems over Lie groups. We consider a bilinear control system with drift and controlled terms that evolves over the special orthogonal group, the general linear group, and the special unitary group. Zero patterns are prescribed for the drift and controlled dynamics with respect to a set of base elements in the corresponding Lie algebra. The drift dynamics must respect a rigid zero-pattern in the sense that the drift takes values as a linear combination of base elements with strictly non-zero coefficients; the controlled dynamics are allowed to follow a free zero pattern with potentially zero coefficients in the configuration of the controlled term by linear combination of the controlled base elements. First of all, for such bilinear systems over the special orthogonal group or the special unitary group, the zero patterns are shown to be associated with two undirected or directed graphs whose connectivity and connected components ensure structural controllability/accessibility. Next, for bilinear systems over the special unitary group, we introduce two edge-colored graphs associated with the drift and controlled zero patterns, and prove structural controllability conditions related to connectivity and the number of edges of a particular color.
