Mehmood, H. (author)
In existing modular adaptive control approaches, the effects of external disturbances such as atmospheric turbulence are often not considered. In real-life flight applications, stochastic atmospheric disturbances can severely degrade the performance of these approaches, resulting in undesired and unpredictable control behavior. In this thesis,...

The effects of horizontal tail geometry and position on longitudinal flapping-wing micro aerial vehicle dynamics were studied using wind tunnel and free-flight experiments. Linearised models were used to analyse the effect on the dynamic properties of the ornithopter. Results show higher steady-state velocity and increased pitch damping for...

This paper presents a novel active gust load alleviation approach within a multi-objective flight control framework developed by NASA for a flexible wing aircraft. The aircraft model is based on the NASA Generic Transport Model (GTM). The wing structures incorporate an aerodynamic control surface known as the Variable Camber Continuous Trailing...

The determination of the safe flight envelope can greatly improve aviation safety. Level Set methods, which can determine the safe flight envelope, have an unfavorable dimensional scaling that complicates an on-line application. The results of a novel method based on multivariate B-splines are presented in this research. Unlike Level Set methods...

Development of adaptive haptic shared control system requires understanding of the adaptive nature of the driver’s neuromuscular system. In this study, linear parameter varying modeling techniques are proposed to identify changes in the admittance of the driver’s arm. The admittance describes the relation between the torque applied to the...

Unmanned aerial vehicle (UAV) applications are increasing and there is a need for safe operations in terms of avoidance. The Velocity Obstacle (VO) method uses position and velocity vectors to determine if a collision is going to happen; an adaptation of the VO- method is called the Selective Velocity Obstacle (SVO) method and adds navigation...

Unmanned Aerial Vehicles (UAVs) can be used to access remote areas that were otherwise inaccessible, for example, for surveillance missions. Collaboration between them can help overcome communication constraints by building airborne relay networks that allow beyond line of sight communication. This research investigates if a single operator can...

Loss Of Control In-flight (LOC-I) is currently the largest cause of accidents for the world wide commercial jet transport fleet. To decrease the occurrence of this type of accident, procedures have been modified and pilot training has been increased. However, current training devices lack the appropriate flight models and motion capabilities to...

The concept of Trajectory Based Operations as proposed by the SESAR and NextGen projects seeks to enhance efficiency and increase airspace capacity by the explicit use of time as the control variable. Nevertheless, the Air Traffic Control system has too many unforeseen events to make it entirely automatic, and adequate decision-support tools...

Govindarajan, N. (author)
This dissertation presents an optimal control framework to determine a collection of open-loop command signals, that mathematically guarantees operation of a dynamical system within prescribed state constraints. The framework is applied to estimate real-time command margins for aircraft control systems so that, safe operation within the flight...

Pool, D.M. (author)
Compared to aircraft, flight simulators are severely limited in their motion envelopes. Presenting the true aircraft motion one-to-one on flight simulators is generally impossible and it is therefore common practice that these motion stimuli are only presented in reduced and attenuated form. Because of a limited understanding of human motion...

Bijl, H.J. (author)
Self-learning controllers offer various strong benefits over conventional controllers, the most important one being their ability to adapt to unexpected circumstances. Their application is however limited, the most important reason being that, for self-learning controllers to work on continuous domains, nonlinear function approximators are...

The thesis describes the algorithms design required to perform in-trail self-spacing during continuous descent approaches. Both distance-based and time-based spacing is treated. The CDA-procedure that is investigated is the Three-Degree Decelerating Approach (TDDA). The results of various off-line and simulator experiments as well as test flight...

The main goal of this thesis is to investigate the potential of the nonlinear adaptive backstepping control technique in combination with online model identification for the design of a reconfigurable flight control system for a modern fighter aircraft. Adaptive backstepping is a recursive, Lyapunov-based, nonlinear design method, that makes use...

Verveld, M.J. (author)
This work addresses the problem of indoor state estimation for autonomous flying vehicles with an optic flow approach. The paper discusses a sensor configuration using six optic flow sensors of the computer mouse type augmented by a three-axis accelerometer to estimate velocity, rotation, attitude and viewing distances. It is shown that the...
