Quantum robust control theory for Hamiltonian and control field uncertainty [PDF]
New Journal of Physics, 2021 Quantum robust control—which can employ fast leading order approximations, slower but more accurate asymptotic methods, or a combination thereof for quantification of robustness—enables control of moments of quantum observables and gates in the presence ...

Passive robust control for uncertain Hamiltonian systems by using operator theory
CAAI Transactions on Intelligence Technology, 2022 In this study, the passivity‐based robust control and tracking for Hamiltonian systems with unknown perturbations by using the operator‐based robust right coprime factorisation method is concerned.

A current value Hamiltonian Approach for Discrete time Optimal Control Problems arising in Economic Growth [PDF]
Journal of Difference Equations and Applications 2021, 2018 Pontrygin-type maximum principle is extended for the present value Hamiltonian systems and current value Hamiltonian systems of nonlinear difference equations for uniform time step $h$. A new method termed as a discrete time current value Hamiltonian method is established for the construction of first integrals for current value Hamiltonian systems of ...

Data-driven Bayesian Control of Port-Hamiltonian Systems [PDF]
arXiv, 2023 Port-Hamiltonian theory is an established way to describe nonlinear physical systems widely used in various fields such as robotics, energy management, and mechanical engineering. This has led to considerable research interest in the control of Port-Hamiltonian systems, resulting in numerous model-based control techniques.

Representation of Hamilton-Jacobi equation in optimal control theory with compact control set [PDF]
SIAM J. Control Optim. 57, 53-77 (2019), 2018 In this paper we study the existence of sufficiently regular representations of Hamilton-Jacobi equations in optimal control theory with the compact control set. We introduce a new method to construct representations for a wide class of Hamiltonians, wider than it was achieved before.

Quantum Property Preservation [PDF]
PRX QuantumQuantum property preservation (QPP) is the problem of maintaining a target property of a quantum system for as long as possible. This problem arises naturally in the context of open quantum systems subject to decoherence.

Hamiltonian control of magnetic field lines: Computer assisted results proving the existence of KAM barriers [PDF]
Journal of Computational Dynamics, 2021 We reconsider a control theory for Hamiltonian systems, that was introduced on the basis of KAM theory and applied to a model of magnetic field in previous articles.
