Strict abnormal extremals in nonholonomic and kinematic control systems
M. Barbero Linan, M. C. Munoz-Lecanda
In optimal control problems, there exist different kinds of extremals, that is, curves candidates to be solution: abnormal, normal and strictly abnormal. The key point for this cla…
Geometric Approach to Pontryagin's Maximum Principle
María Barbero-Liñán, Miguel C. Muñoz-Lecanda
Since the second half of the 20th century, Pontryagin's Maximum Principle has been widely discussed and used as a method to solve optimal control problems in medicine, robotics, fi…
Constraint Algorithm for Extremals in Optimal Control Problems
Maria Barbero-Liñan, Miguel C. Muñoz-Lecanda
A geometric method is described to characterize the different kinds of extremals in optimal control theory. This comes from the use of a presymplectic constraint algorithm starting…
Some geometric aspects of variational calculus in constrained mechanics
Xavier Gracia, Jesus Marin-Solano, Miguel-C. Munoz-Lecanda
We give a geometric description of variational principles in mechanics, with special attention to constrained systems. For the general case of nonholonomic constraints, a unified v…
Reduction of Presymplectic Manifolds with Symmetry
A. Echeverrí a-Enrí quez, M. C. Muñoz-Lecanda, N. Román-Roy
Actions of Lie groups on presymplectic manifolds are analyzed, introducing the suitable comomentum and momentum maps. The subsequent theory of reduction of presymplectic dynamical…
