Variational Dissipative Mechanics on Lie Algebroids

Alexandre Anahory Simoes, Leonardo Colombo

We formulate a Herglotz-type variational principle on a Lie algebroid and derive the corresponding Euler--Lagrange--Herglotz equations for a Lagrangian depending on an additional s…

Mechanical Hamiltonization of unreduced -simple Chaplygin systems

Alexandre Anahory Simoes, Juan Carlos Marrero, David Martín de Diego

In this paper, we prove that the trajectories of unreduced -simple Chaplygin kinetic systems are reparametrizations of horizontal geodesics with respect to a modified Riemannian…

Symmetry reduction and reconstruction in contact geometry and Lagrange-Poincaré-Herglotz equations

Alexandre Anahory Simoes, Leonardo Colombo, Manuel de Leon +2

In this paper, we investigate the reduction process of a contact Lagrangian system whose Lagrangian is invariant under a group of symmetries. We give explicit coordinate expression…

Comparison of two numerical methods for Riemannian cubic polynomials on Stiefel manifolds

Alexandre Anahory Simoes, Leonardo Colombo, Fátima Silva Leite

In this paper we compare two numerical methods to integrate Riemannian cubic polynomials on the Stiefel manifold . The first one is the adjusted de Casteljau alg…

Optimal Control of Incompressible Ideal Flows with Obstacle Avoidance

Alexandre Anahory Simoes, Anthony Bloch, Leonardo Colombo

It was shown in \cite{bloch2000optimal} that an optimal control formulation for incompressible ideal fluid flow yields Euler's equations. In this paper, we consider a variational o…

On the Geometry of Virtual Nonlinear Nonholonomic Constraints

Efstratios Stratoglou, Alexandre Anahory Simoes, Anthony Bloch +1

Virtual constraints are relations imposed on a control system that become invariant via feedback control, as opposed to physical constraints acting on the system. Nonholonomic syst…
