Stability of Relative Equilibria with Singular Momentum Values in Simple Mechanical Systems
نویسنده
چکیده
A method for testing Gμ-stability of relative equilibria in Hamiltonian systems of the form “kinetic + potential energy” is presented. This method extends the Reduced Energy-Momentum Method of Simo et al. to the case of non-free group actions and singular momentum values. A normal form for the symplectic matrix at a relative equilibrium is also obtained.

Stability and Drift of Underwater Vehicle Dynamics: Mechanical Systems with Rigid Motion Symmetry
This paper develops the stability theory of relative equilibria for mechanical systems with symmetry. It is especially concerned with systems that have a noncompact symmetry group, such as the group of Euclidean motions, and with relative equilibria for such symmetry groups. For these systems with rigid motion symmetry, one gets stability but possibly with drift in certain rotational as well as...
متن کاملRelative Equilibria at Singular Points of the Moment Map
We prove a criterion for stability of relative equilibria in symmetric Hamiltonian systems at singular points of the momentum map. This generalizes a theorem of G.W. Patrick. The method of the proof is also useful in studying the bifurcation of relative equilibria.
متن کاملBifurcations of relative equilibria near zero momentum in Hamiltonian systems with spherical symmetry
For Hamiltonian systems with spherical symmetry there is a marked difference between zero and non-zero momentum values, and amongst all relative equilibria with zero momentum there is a marked difference between those of zero and those of non-zero angular velocity. We use techniques from singularity theory to study the family of relative equilibria that arise as a symmetric Hamiltonian which ha...
متن کاملThe Energy-Momentum Method for the Stability of Nonholonomic Systems
In this paper we analyze the stability of relative equilibria of nonholonomic systems (that is, mechanical systems with nonintegrable constraints such as rolling constraints). In the absence of external dissipation, such systems conserve energy, but nonetheless can exhibit both neutrally stable and asymptotically stable, as well as linearly unstable relative equilibria. To carry out the stabili...
متن کاملSymmetry Breaking for Toral Actions in Simple Mechanical Systems
For simple mechanical systems, bifurcating branches of relative equilibria with trivial symmetry from a given set of relative equilibria with toral symmetry are found. Lyapunov stability conditions along these branches are given.
