Abstract

The free motion of a two-link manipulator as a nonlinear system is studied, and the interrelation between the Lyapunov function (criteria of dynamic stability) and entropy production of a mechanical motion for intelligent robust force control are introduced. A new physical measure of controllability as minimum entropy production is proposed and discussed, and the efficiency of the new physical measure for global control object stability was examined by 3D computer simulation.
