Optimization Provenance of Whiplash Compensation for Flexible Space Robotics
Aerospace, 2019 Automatic controls refer to the application of control theory to regulate systems or processes without human intervention, and the notion is often usefully applied to space applications.

Search complexity and resource scaling for the quantum optimal control of unitary transformations
, 2010 The optimal control of unitary transformations is a fundamental problem in quantum control theory and quantum information processing. The feasibility of performing such optimizations is determined by the computational and control resources required ...

Efficient control of accelerator maps [PDF]
, 2011 Recently, the Hamiltonian Control Theory was used in [Boreux et al.] to increase the dynamic aperture of a ring particle accelerator having a localized thin sextupole magnet. In this letter, these results are extended by proving that a simplified version

Lyapunov-based fixed-time stabilization control of quantum systems
Journal of Automation and Intelligence, 2022 In this paper, we consider the fixed-time stabilization control problem of quantum systems modeled by Schrödinger equations. Firstly, the Lyapunov-based fixed-time stability criterion is extended to finite-dimensional closed quantum systems in the form ...

Port-Hamiltonian systems: an introductory survey [PDF]
, 2006 The theory of port-Hamiltonian systems provides a framework for the geometric description of network models of physical systems. It turns out that port-based network models of physical systems immediately lend themselves to a Hamiltonian description ...

Quantifying the Unitary Generation of Coherence From Thermal Quantum Systems
, 2019 The unitary generation of coherence from an incoherent thermal state is investigated. We consider a completely controllable Hamiltonian allowing to generate all possible unitary transformations. Optimizing the unitary control to achieve maximum coherence

A new approach to the solution of free rigid body motion for attitude manoeuvers [PDF]
, 2013 A Hamiltonian formulation of free rigid body motion defined on the Special Unitary Group SU(2) is used to integrate the system to obtain a convenient quaternion representation for attitude engineering applications.

Decoupling dipolar interactions in dense spin ensembles
Physical Review ResearchDense spin ensembles in solids present a natural platform for studying quantum many-body dynamics. Multiple-pulse coherent control can be used to manipulate the magnetic dipolar interaction between the spins to engineer their dynamics.

Robust PI passivity-based control of nonlinear systems: Application to port-Hamiltonian systems and temperature regulation [PDF]
American Control Conference, 2015 This paper deals with the problem of control of partially known nonlinear systems, which have an open-loop stable equilibrium, but we would like to add a PI controller to regulate its behavior around another operating point.

Discrete Hamilton-Jacobi Theory
, 2011 We develop a discrete analogue of Hamilton-Jacobi theory in the framework of discrete Hamiltonian mechanics. The resulting discrete Hamilton-Jacobi equation is discrete only in time.
