On Data-Driven Modeling, Robust Control, and Analysis for Complex Dynamical Systems
… techniques, nonlinear systems are represented as uncertain linear models. A significant contribution of this dissertation is the development of data-driven approaches to generate these uncertain linear models, which capture the behavior of nonlinear systems reasonably well over the considered …

Maneuver-Based Motion Control of a Miniature Helicopter
… as a performance measure while accounting for uncertain initial states. Each control approach is evaluated in closed-loop simulation with a nonlinear helicopter model. The controllers are set to drive the helicopter model to track desired trajectories in the presence of disturbances such as …

Model Abstraction in Dynamical Systems: Application to Mobile Robot Control
… the relationship between the evolution of uncertain initial conditions in abstracted control systems. It is shown that a control system abstraction can capture the time evolution of the uncertainty in the original system by an appropriate choice of control input. Abstracted control systems …

Stochastic Ocean Forecasting with the Dynamically Orthogonal Primitive Equations
… a streamlined process to create multi-region initial conditions for the DO-PE framework, starting from temporally and spatially sparse historical data. The process presented allows us to start from a relatively small but relevant set of measured temperature and salinity historical vertical …

A Low-Cost Unmanned Aerial Vehicle Research Platform: Development, Modeling and Advanced Control Implementation
… trajectories despite the various modeling uncertainties, exogenous disturbances and measurement noise. These switched controllers are composed of discrete-time linear sub-controllers designed separately for a subset of the pre-specified primitives, with the uncertain initial conditions, …

On the Security and Reliability of Fixed-Wing Unmanned Aircraft Systems
… array of geometric paths. Next, convex synthesis conditions are developed for control of distributed systems with uncertain initial conditions, whereby independent norm constraints are placed on the disturbance input and the uncertain initial state. Using this approach, we design a distributed …
