Ensemble control of Hamiltonian systems
… the conditions under which a particular kind of ensemble control system is controllable. Previous studies on this topic have tended to make simplifying assumptions on the systems in view, and this paper attempts to remove some of those assumptions. Even in a non-linear ensemble system, it can be …

Ensemble control of robotic systems
In this dissertation, we apply the framework of ensemble control theory to derive an approximate steering algorithm for two classical robotic systems---the nonholonomic unicycle and the plate-ball manipulator---in the presence of model perturbation that scales all inputs by an unknown but bounded …

Control of Deterministic and Stochastic Linear Ensemble Systems
… parameters. This factor arises in practical control problems in many areas of science and engineering when there is uncertainty in the parameters of a single control system, or when a collection of structurally similar systems with variations in common parameters must be steered using a …

Optimal Control and Synchronization of Dynamic Ensemble Systems
<p>Ensemble control involves the manipulation of an uncountably infinite collection of structurally identical or similar dynamical systems, which are indexed by a parameter set, by applying a common control without using feedback. This subject is motivated by compelling problems in quantum control, …

Optimal Control of Inhomogeneous Ensembles
… parameters across the collection, or ensemble. Our goal is to steer the family of systems from an initial state: or pattern) to a desired state: or pattern) with the same common control while compensating for the inherent dispersion caused by the inhomogeneous parameter values. We …

Geometric Control of Ensemble Systems
… examples range from excitations of spin ensembles in nuclear magnetic resonance (NMR) spectroscopy and imaging (MRI), and desynchronization of neuron ensembles for the treatment of neurological disorders, to approximate steering of robot swarm under bounded model perturbation. However, …

ECoG correlates of visuomotor transformation, neural plasticity, and application to a force-based brain computer interface
… of extracting more independent signals for BCI control within less cortical real-estate. However, most control signals to date, whether within the field of ECoG or any of the more seasoned recording techniques, have translated their control signals to kinematic control parameters: i.e. position …

Feedback control of many differential-drive robots with uniform control inputs
We describe a method of feedback position control for an ensemble of robots with unicycle kinematics under the constraint that every robot receives ex- actly the same global control inputs. Each robot in the ensemble scales its given control inputs by a bounded model parameter and thus may achieve …

Robust Engineering of Dynamic Structures in Complex Networks
… role in determining the functioning of the ensemble. Robust and optimal control of such large collections of dynamical units remains a grand challenge, especially, when these units interact and form a complex network. Motivated by compelling practical problems in power systems, neural …
