Interpolation Methods for the Model Reduction of Bilinear Systems
Bilinear systems are a class of nonlinear dynamical systems that arise in a variety of applications. In order to obtain a sufficiently accurate representation of the underlying physical phenomenon, these models frequently have state-spaces of very large dimension, resulting in the need for model …

Structural controllability of driftless bilinear control systems
… the structural controllability of driftless bilinear systems with sparse matrices. We begin with a rigorous introduction to the controllability of nonholonomic nonlinear systems. We present the notion of structural controllability and the fact that the controllability of linear systems is a …

Geometric Control of Ensemble Systems
… manipulation of large populations of dynamical systems is prevalent in numerous research areas of science and engineering. Prominent examples range from excitations of spin ensembles in nuclear magnetic resonance (NMR) spectroscopy and imaging (MRI), and desynchronization of neuron ensembles for …

Optimal Control and Synchronization of Dynamic Ensemble Systems
… 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, sensorless robotic manipulation, and neural engineering, which involve ensembles …

Using Pulse R -Factors to Estimate Structural Response to Earthquake Ground Motions
… period of the ground motion. The response of bilinear systems to simple pulses was examined, and simple analytical expressions for the R-factors of short period systems having positive post-yield stiffness and long period elasto-plastic systems are reported. The equal energy rule is found to …

Finite Horizon Optimality and Operator Splitting in Model Reduction of Large-Scale Dynamical System
Simulation, design, and control of dynamical systems play an important role in numerous scientific and industrial tasks. The need for detailed models leads to large-scale dynamical systems, posing tremendous computational difficulties when employed in numerical simulations. In order to overcome …

Robust Engineering of Dynamic Structures in Complex Networks
<p>Populations of nearly identical dynamical systems are ubiquitous in natural and engineered systems, in which each unit plays a crucial role in determining the functioning of the ensemble. Robust and optimal control of such large collections of dynamical units remains a grand challenge, …

Approximation of Parametric Dynamical Systems
Dynamical systems are widely used to model physical phenomena and, in many cases, these physical phenomena are parameter dependent. In this thesis we investigate three prominent problems related to the simulation of parametric dynamical systems and develop the analysis and computational framework …
