Oculometric Indices of Simulator and Aircraft Motion
… on eye-scan behavior of both simulator and aircraft motion, the sensitivity of an oculometric measure to motion effects was demonstrated. "Fixation Time", defined as the time the eyes spend at a particular location before moving on (saccade) to another fixation point, was found to be …

Nonlinear Observers for Aircraft Maneuvering in Wind
… wind estimation methods that infer wind from aircraft motion. However, typical model-based estimators lack rigorous stability guarantees across the full flight envelope --- a major limitation for safety-critical aerospace applications. This dissertation addresses these gaps by advancing …

Dynamics and Control of Flexible Aircraft
… disciplines pertinent to the flight of flexible aircraft, namely, analytical dynamics, structural dynamics, aerodynamics and controls. The unified formulation is based on fundamental principles and incorporates in a natural manner both rigid body motions of the aircraft as a whole and elastic …

Identification of Unsteady Flight Dynamic Models and Model-based Wind Estimation with Flight Test Validation
… boundary layer (ABL). Small, low-cost, uncrewed aircraft (drones) can be used to measure wind and a distribution of these vehicles could potentially provide measurements with much greater density and resolution, in both space and time, than current methods allow. To measure wind, a drone could be …

Predicting pilot intent and aircraft trajectory in uncontrolled airspace
… rely on propagating the current velocity of the aircraft are not well suited to long-term prediction of pilot behavior in this environment. This thesis proposes a new probabilistic trajectory prediction method within a hierarchical pilot behavior framework that extends the model proposed by Liao …

Time Delay Mitigation in Aerial Telerobotic Operations Using Predictors and Predictive Displays
… gimbal-camera system to a moving 6 DoF aircraft. Specifically, it talks about a novel extended Kalman filter (EKF)-based nonlinear predictor – the extended Kalman predictor (EKP) – and compares its performance with two linear predictors, the Smith predictor (SP) and the Kalman predictor …

Strain Gauge Utilization for Aerial Vehicle Dynamic Load Measurement
… estimation system for a quadrotor unmanned aircraft, and (3)compare the developed strain gauge-based thrust estimation technique with an indirect real time parameter estimation technique for motor fault detection. In pursuit of the first thesis objective, a load distribution measurement …

Two-Step System Identification and Primitive-Based Motion Planning for Control of Small Unmanned Aerial Vehicles
This dissertation addresses motion planning, modeling, and feedback control for autonomous vehicle systems. A hierarchical approach for motion planning and control of nonlinear systems operating in obstacle environments is presented. To reduce computation time during the motion planning process, …
