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 ...

Energy spectrum and quantum phase transition of the coupled single spin and an infinitely coordinated Ising chain [PDF]
Beilstein Journal of NanotechnologyIn this work we consider a spin model composed of a single spin and connected to an infinitely coordinated Ising chain. Theoretical models of this type arise from various fields of theoretical physics, such as theory of open systems, quantum control, and

Hamiltonian theory applied to ameliorate the complexity of tcp network congestion control
2017 IEEE International Conference on Systems, Man, and Cybernetics (SMC), 2017 An active queue management controller based on Hamiltonian energy theory for a class of nonlinear TCP network congestion system in the p resence of uncertain parameters and unknown external disturbances is derived. The restriction of inequality assumption is eliminated by introducing the MiniMax methods into dissipation Hamilton system.

A family of virtual contraction based controllers for tracking of flexible‐joints port‐Hamiltonian robots: Theory and experiments [PDF]
International Journal of Robust and Nonlinear Control, 2020 SummaryIn this work, we present a constructive method to design a family of virtual contraction based controllers that solve the standard trajectory tracking problem of flexible‐joint robots in the port‐Hamiltonian framework. The proposed design method, called virtual contraction based control, combines the concepts of virtual control systems and ...

Co-ordinated emergency control of generator-tripping and SMES based on Hamiltonian system theory
International Journal of Electrical Power & Energy Systems, 2005 This paper presents a novel scheme for the co-ordinated emergency control of generator-tripping control and Super-conducting Magnetic Energy Storage (SMES). The mathematical foundation of the scheme is based on the proposal of a new Lyapunov function of power systems transient stability analysis derived according to the Hamiltonian systems theory ...
