Hamiltonian functional and relevant Lagrange equation system are popular tools in investigation of dynamic systems. Various generalizations enable to extend the class of problems concerned slightly beyond conventional limits of a Hamiltonian system. This strategy is very effective particularly concerning 2D and simpler 3D systems. However, the governing differential systems of most non-holonomic 3D systems suffer from inadequate complexity, when deduced using this way. Any analytical investigation of such a governing system is rather impossible and its physical interpretation can be multivalent. For easier analysis particularly of systems with non-holonomic constraints the Appell-Gibbs approach seems to be more effective providing more transparent governing systems.
