A Nonlinear Control Design Strategy for Piloting Fixed Wing Aircrafts

Robust MRAC for a Wing Rock Phenomenon in Delta Wing Aircrafts

Wing rock phenomenon is an undesired motion appears in high angles of attack where a rolling in the aircraft in positive and negative roll angles with specified amplitude and frequency is occurred. In this paper two adaptive controllers suggested to control the rolling dynamics under wing rock phenomenon for a delta wing aircraft with presence of disturbance. Disturbance was considered as unmat...

Design and Implementation of Nonlinear Control Systems for Rotary and Fixed Wing Uavs

The aim of this paper is to present a novel approach for the design and implementation of onboard nonlinear control systems for different types of unmanned air vehicles. The essential difficulty of creating such controllers is the inherent nonlinearity of the dynamics of the system, which also introduces a great complexity. Our proposed approach relies on an automatic state dependent coefficien...

Nonlinear Control of Fixed-Wing Unmanned Aerial Vehicles

Adaptive Nonlinear Model Predictive Path Tracking Control for a Fixed-Wing Unmanned Aerial Vehicle

This paper presents an adaptive Nonlinear Model Predictive Control (NMPC) for the path tracking control of a fixed-wing unmanned aircraft. The objective is to minimize the mean and maximum error between the reference trajectory and the UAV. Navigating in a cluttered environment requires accurate tracking. However linear controllers cannot provide good tracking performance due to nonlinearities ...

Agile Flight Control Techniques for a Fixed-Wing Aircraft

As unmanned aerial vehicles (UAVs) become more involved in challenging mission objectives, the need for agility controlled flight becomes more of a necessity. The ability to navigate through constrained environments as well as quickly maneuver to each mission target is essential. Currently, individual vehicles are developed with a particular mission objective, whether it be persistent surveilla...
