Online Learning in Control Theory
… we study two classes of problems in optimal control theory involving unknown parameters, with focus on Linear-Quadratic-Gaussian systems. In the first problem, the control system is known and linear, and a sequence of quadratic cost functions is revealed to the controller in hindsight. The …

Moment method in distributed control theory
… and solve moment problems which arise from controllability questions posed on the wave equation and the Mead-Markus model of a beam.</p>

Contributions to model following control theory
… for linear and nonlinear perfect model following control problems is introduced, and the associated control laws developed. The error dynamics of such systems are analyzed with respect to stability of the error. The effects on the error dynamics of measurement errors and parameter variations are …

Feedback Control Theory in Stochastic Dynamical Systems
… which includes stochastic behavior. Feedback control theory is designed to use information from the current state of the system in order to temper the final state toward the desired outcome. In this dissertation, I perform studies on two choices of classic and quantum dynamical systems to …

Two new extensions to L1 adaptive control theory
… introduces two new extensions to L1 adaptive control theory. The first is an L1 adaptive state feedback controller with generalized proportional adaptation law for a class of linear systems with input–gain uncertainties and unmatched nonlinear disturbances. The proportional adaptation law …

An application of optimal control theory in welfare economics
We consider the maximization of a functional representing social welfare over continuous time. A social welfare functional (SWF) is an integral that models social welfare as a function of individual consumption, individual utility of consumption and the value of utility aggregated across …

A variational approach to local optimality in control theory
A new approach to control theory is investigated in this thesis. The approach is based on a locally specified state space model of the control dynamics; together with a goal function, which defines a generalized distance from each state position to the desired equilibrium point or trajectory. A …

Modern control theory application in mill main drive design
Modern Control Theory is applied to analyze an existing aluminum mill drive, which was originally designed by Classical Methods. The system is studied with Optimal Control and z-transform zero-pole locus tools. The results and also the original design are compared with the performance of …

Model-Based and Data-Driven Covariance Control: Theory and Applications
Control under uncertainty is at the cornerstone of modern control theory, yet traditional methods often struggle with ensuring safety and robustness in stochastic environments. This dissertation advances the theory of covariance steering (CS), which shifts the focus from controlling specific system …

Development of the finite and infinite interval learning control theory
… in real systems, Iterative Learning Control (ILC) is extended to systems with deadzone/backlash, which provides a simple way to deal with such high nonlinearities. Benefiting from Composite Energy Function (CEF), the robust FIL is further proposed to handle norm-bounded uncertainties. …

Optimal control theory applied to ship maneuvering in restricted waters
… proximity to rigid boundaries or other vessels. Controlling the effects of these forces has been traditionally handled by experienced helmsmen. The purpose of this research is to apply modern optimal control theory to these maneuvering scenarios in order to show that helmsman may some day be …

Explaining Variance in Affect Control Theory: Cultural Consensus, Deflection, and Redefinition
<p>Affect Control Theory (ACT) conceives of affective sentiments as shared</p><p>meanings among individuals within a single culture. Recognizing the theory's potential</p><p>to explain cultural differences and behavior patterns, many researchers aim to test and</p><p>apply ACT's insights to within- …
