Model Reduction for Linear Time-Varying Systems
The thesis treats model reduction for linear time-varying systems. Time-varying models appear in many fields, including power systems, chemical engineering, aeronautics, and computational science. They can also be used for approximation of time-invariant nonlinear models. Model reduction is a topic …

A Linear, Time-Varying System Framework for Bandlimited Signal Extrapolation
… theory for modeling, analyzing, and designing linear, time-varying systems is used to study several aspects of bandlimited signal extrapolation, the problem of reconstructing the whole of a bandlimited signal from a known piece. The extrapolation of both continuous-time and discrete-time …

Learning-based Optimal Control of Time-Varying Linear Systems Over Large Time Intervals
… problem of two-point boundary optimal control of linear time-varying systems with unknown model dynamics using reinforcement learning. Leveraging singular perturbation theory techniques, we transform the time-varying optimal control problem into two time-invariant subproblems. This allows the …

A general linear systems theory on time scales : transforms, stability, and control.
In this work, we examine linear systems theory in the arbitrary time scale setting by considering Laplace transforms, stability, controllability, and realizability. In particular, we revisit the definition of the Laplace transform by Bohner and Peterson in [10]. We provide sufficient conditions for …

Observability and observer design for switched linear systems
<p>Hybrid vehicles, HVAC systems in new/old buildings, power networks, and the like require safe, robust control that includes switching the mode of operation to meet environmental and performance objectives. Such switched systems consist of a set of continuous-time dynamical behaviors whose …

System Identification via the Proper Orthogonal Decomposition
… application to large, complex structures can be time-consuming and errors in the modeling process may negatively affect the accuracy of analyses based on the model. System identification techniques attempt to circumvent these problems by using experimental response data to characterize or …

Fast Parameter Learning in Adaptive Systems
… control pertains to the control of dynamic systems exposed to parametric uncertainties in real-time with guarantees of stability and control goals of tracking. A central part of adaptive control is parameter estimation. Real-time adaptive control requires parameter estimation to occur …

Reduced order modeling of convection-dominated flows, dimensionality reduction and stabilization
… of solution arising from convection-dominated nonlinear physical systems. Although existing nonlinear manifold learning methods seem to be compelling tools to reduce the dimensionality of data characterized by large Kolmogorov n-width, they typically lack a straightforward mapping from the latent …

On variational principles for dissipative networks and systems
Dynamical equations for dissipative systems are in general not derivable from a Lagrangian, but variational principles can nevertheless be formulated using auxiliary variables or a multiplying factor. Both methods are examined, generalized, and applied to some dissipative systems. Composite …
