ABSTRACT The paper finds the singular points from which (to which) the generically accessible system is not weakly reachable (controllable) in k steps. These points are found with the help of the space of vector fields, being the discrete-time analogue of the strong accessibility distribution. Unlike in the continuous-time case, a separate object is needed to find the singular points related to weak reachability.

离散时间非线性系统的弱可达性和可控性：泛型方法和奇异点

摘要 本文在 k 步中找到了通用可访问系统从其（到）不是弱可达（可控）的奇异点。这些点是在向量场空间的帮助下找到的，是强可达性分布的离散时间模拟。与连续时间情况不同，需要一个单独的对象来找到与弱可达性相关的奇异点。
