Abstract
In this paper we show how to use periodic forcing to solve the
constructive controllability problem for drift-free, left-invariant
systems on matrix Lie groups with fewer controls than states. In
particular,
we prove a second-order averaging theorem applicable to systems evolving
on
general matrix Lie groups. Using this theorem, we show how to construct
open
loop controls for complete controllability of systems that require up to
depth-one Lie brackets to satisfy the Lie algebra controllability rank
condition. We apply these results to the attitude control problem with
only
two controls available and to
the unicycle motion planning problem.
