Optimal control of a Bose-Einstein condensate in an opticallattice: the non-linear and two-dimensional cases

open access: yesFrontiers in Quantum Science and Technology
We numerically study the optimal control of an atomic Bose-Einstein condensate in an optical lattice. We present two generalizations of the gradient-based algorithm, GRAPE, in the non-linear case and for a two-dimensional lattice.

Optimal Control of Polymer Flooding Based on Maximum Principle

open access: yes, 2012
Polymer flooding is one of the most important technologies for enhanced oil recovery (EOR). In this paper, an optimal control model of distributed parameter systems (DPSs) for polymer injection strategies is established, which involves the performance ...

Some Applications of the Maximum Principle to Second-Order Systems, Subject to Input Saturation, Minimizing Error, and Effort

open access: yes, 1964
The optimal controls for various types of performance criteria are investigated for second-order systems by means of the Pontryagin’s Maximum Principle. Optimal control solutions for several examples are shown. The results presented show widely different

Pontryagin’s maximum principle for the Loewner equation in higher dimensions

open access: yes, 2014
In this paper we develop a variational method for the Loewner equation in higher dimensions. As a result we obtain a version of Pontryagin's maximum princi-ple from optimal control theory for the Loewner equation in several complex variables.

The Deterministic Impulse Control Maximum Principle in Operations Research: Necessary and Sufficient Optimality Conditions (replaces CentER DP 2011-052) [PDF]

open access: yes
This paper considers a class of optimal control problems that allows jumps in the state variable. We present the necessary optimality conditions of the Impulse Control Maximum Principle based on the current value formulation.

Necessity of the Transversality Condition for Stochastic Models with Bounded or CRRA Utility [PDF]

open access: yes
This paper shows that the standard transversality condition (STVC) is nec-essary for optimality in stochastic models with bounded or constant-relative-risk- aversion (CRRA) utility under fairly general conditions.
