Discrete Variational Optimal Control

, 2012
This paper develops numerical methods for optimal control of mechanical systems in the Lagrangian setting. It extends the theory of discrete mechanics to enable the solutions of optimal control problems through the discretization of variational ...

Optimal and adaptive control of underwater vehicles [PDF]

Modeling, Identification and Control, 1994
This article contains a continuous-time optimal and adaptive control scheme for underwater vehicles moving in six degrees of freedom. The control scheme is an extension of the algorithm ofJohansson (1990) and a modification of the algorithm found in ...

On an optimal control problem

Journal of Computational and Applied Mathematics, 1998
AbstractIn this paper, we applied the finite differences method to the solution of variational problem of an inverse problem for the Scrödinger equation with a final functional. These types of problems arise in various fields in quantum-mechanical, nuclear physics and modern physics [2, 11].
