Adaptive Robust Control
… a novel approach to the problem of adaptive robust control. The essential idea involved is to fragment the modeling uncertainty in a physical plant into "small" families of plant models for which robust linear time-invariant controllers can be readily designed. We then implement a convex …

Robust Control of Stochastic Nonlinear Systems
… stochastic games and risk-sensitive stochastic control, we obtain a minimax state-feedback control law that is both locally optimal and globally inverse optimal. Furthermore, the closed-loop system is absolutely stable in the presence of stochastic uncertainty disturbances.

Robust Control for Inter-area Oscillations
… state feedback. The LMI optimization finds a control law that stabilizes several contingencies simultaneously using a polytopic model of the system. However, the number of cases to be considered is limited by computational complexity which increases the chances of infeasibility. In order to …

Robust Control for Hybrid, Nonlinear Systems
We develop the robust control theories of stopping-time nonlinear systems and switching-control nonlinear systems. We formulate a robust optimal stopping-time control problem for a state-space nonlinear system and give the connection between various notions of lower value function for the …

Multidimensional Linear Systems and Robust Control
… interpolation theory to solve the $H^{\infty}$ control problem for $d$-D linear systems. We first review the classical discrete-time 1D linear system in the operator theoretical viewpoint followed by the formulations of the so-called Givone-Roesser and Fornasini-Marchesini models. Application of …

Nonlinear Robust Control Synthesis Methods for Spacecraft Applications
… focuses on practical methods for constructing robust nonlinear control systems. In general, the development of such control systems is characterized by the solution to one or more Hamilton-Jacobi partial differential equations (HJE). However, no general analytical solution has yet been obtained …

Weight selection in robust control : an optimisation approach
… which facilitate the selection of weights in robust control techniques. The robust control paradigms investigated in this thesis are ?-synthesis and H<sub>?</sub> loop-shaping, as these techniques offer a systematic framework for synthesising sensible controllers that meet performance …

Robust control of a flexible-hull propulsion system
… fish-like propulsion systems with the Vorticity Control Unmanned Underwater Vehicle (VCUUV) project. The VCUUV is a fully autonomous robotic fish, which employs a flexible tail structure for propulsion and maneuvering. This paper describes the design, implementation, and testing of a control …

Reinforcement learning for multi-agent and robust control systems
… of Go, playing real-time strategy games, robotic control, and autonomous driving. Motivated by these empirical successes, research toward theoretical understandings of RL algorithms has also re-gained great attention in recent years. In this dissertation, our goal is to contribute to these efforts …
