控制仿射系统的几何

Geometry of Control-Affine Systems

Jeanne N. Clelland, Christopher G. Moseley, George R. Wilkens

摘要:

受最优控制理论中控制仿射系统的启发,我们引入了流形X上点仿射分布的概念,即,仿射分布F以及包含在F中的可分辨向量场。当dim(X)=n,rank(F)=n-1,以及当dim(X)=3,rank(F)=1时,我们计算常型点仿射分布的局部不变量。与线性分布不同,线性分布的特征在于整数值不变量-即秩和增长向量-当dim(X)<=4时,我们发现局部不变量依赖于任意函数,即使是2维流形上的秩1点仿射分布。

英文摘要:

Motivated by control-affine systems in optimal control theory, we introduce the notion of a point-affine distribution on a manifold X - i.e., an affine distribution F together with a distinguished vector field contained in F. We compute local invariants for point-affine distributions of constant type when dim(X)=n, rank(F)=n-1, and when dim(X)=3, rank(F)=1. Unlike linear distributions, which are characterized by integer-valued invariants - namely, the rank and growth vector - when dim(X)<=4, we find local invariants depending on arbitrary functions even for rank 1 point-affine distributions on manifolds of dimension 2.
