Аннотация:
In this paper we study the global dynamics of the inverted spherical pendulum with
a vertically rapidly vibrating suspension point in the presence of an external horizontal periodic
force field. We do not assume that this force field is weak or rapidly oscillating. Provided that
the period of the vertical motion and the period of the horizontal force are commensurate,
we prove that there always exists a nonfalling periodic solution, i. e., there exists an initial
condition such that, along the corresponding solution, the rod of the pendulum always remains
above the horizontal plane passing through the pivot point. We also show numerically that
there exists an asymptotically stable nonfalling solution for a wide range of parameters of the
system.
Ключевые слова:
