In this paper we derive and analyze a discontinuous stabilizing feedback fo
r a Lie algebraic generalization of a class of kinematic nonholonomic syste
ms introduced by Brockett [New Directions in Applied Mathematics, P. Hilton
and G. Young, eds., Springer-Verlag, New York, 1982, pp. 11-27]. The algor
ithm involves discrete switching between isospectral and norm-decreasing fl
ows. We include a rigorous analysis of the convergence.
