Unmanned Aerial Vehicles (UAVs) offer a wide range of interesting military and commercial
applications at reduced costs. A couple of their more interesting characteristics include: They …

A quadrotor is a rotorcraft capable of hover, forward flight, and VTOL and is emerging as a
fundamental research and application platform at present with flexibility, adaptability, and …

In this paper, a novel nonlinear control strategy along with its simulation for a quadrotor
helicopter is proposed. The normal 6-DOF dynamic model of the quadrotor based on the …

This paper deals with the design and implementation of a nonlinear control algorithm for the
attitude tracking of a four-rotor helicopter known as quadrotor. This algorithm is based on the …

In this paper, a disturbance observer-based quadrotor attitude controller for aggressive
maneuvering is presented. The controller is made up of the cascade connection between …

A revisited quadrotor model is proposed, including in particular the so-called rotor drag. It
differs from the model usually considered, even at first order, and much better explains the …

This paper presents a reliable and novel quadrotor flight control system designed to
enhance trajectory tracking performance, robustness and adaptiveness against the …

In this paper, we present a detailed dynamic and aerodynamic model of a quadrotor that can
be used for path planning and control design of high performance, complex and aggressive …

The paper focuses on mathematical modelling of a quadrotor and identification of
parameters used in presented models. There are several models of the quadrotor that can …

Remote sensing has traditionally be done with satellites and manned aircraft. While these
methods can yield useful scientific data, satellites and manned aircraft have limitations in …
