Abstract:

For the bilinear control system $$\dot{x}=(A+u\ B )x, x \in R^n, u \in R,\ $$ where $$A\ $$ is an $$\ n \times n$$ essentially nonnegative matrix, and $$B$$ is a diagonal matrix, the following controllability problem is investigated: can any two points with positive coordinates be joined by a trajectory of the system? For $$n>2 \ $$, the answer is negative in the generic case: hypersurfaces in $$R^n$$ are constructed that are intersected by all the trajectories of the system in one direction.
