Dynamics of Nonholonomic Systems

Non-Holonomic Stability Aspects of Piecewise-Holonomic Systems
Ruina, A., This paper demonstrates by means of a simple example that systems that are piecewise holonomic but have intermittent contact inherit some of the stability properties of non-holonomic systems.

Motions and Stability Of A Piecewise Holonomic System: The Discrete Chaplygin Sleigh
Coleman, M, Holmes, P. This paper discusses the dynamics and stability of a piecewise holonomic mechanical system as a function of mass distribution and geometry. It further explores the ideas presented in the above paper. Regular and Chaotic Dynamics vol. 4 no. 2 pp. 1-23, 1999.   pdf (1621k)    ps (3484k)    ps.Z (850k)

The symmetry of some of the simple non-holonomic examples precludes assymtotic stability.
