Further Results On Global Controllability of Affine Nonlinear Systems

Most of the existing results on controllability of nonlinear systems are concerned with local controllability. In this paper, we present some further results on global controllability of two classes of affine nonlinear systems, by using the techniques developed recently by Sun and Guo (2005). The first class is planar affine nonlinear systems with one singular point, the second class is high-dimensional affine nonlinear systems with special structure.
