Micro-Unmanned Air Vehicles (Micro-UAVs), especially quadrotor UAVs, have been widely
used in recent years because of their simple structure and convenient operation. However …

The research topic of VTOL (vertical take-off and landing) fixed wing (VFW) is gaining
significant attention, particularly in the transition phase from VTOL to fixed wing and vice …

Nonlinear control laws often need to be implemented with digital hardware. Use of digital
control systems leads to communication/processing delays which are widely neglected in …

This paper presents an adaptive sliding mode-based active disturbance rejection control
(ASM-ADRC) strategy for the altitude and attitude control of an unmanned quadcopter with …

In this paper, a control law is presented to regulate yaw angle of an unmanned helicopter.
The proposed law has been designed to control yaw angle at turning manoeuvre, where the …

In this paper, the problem of position control for the quadrotor is solved when attitude
information is not available. Firstly, the quadrotor model is successfully transformed into a …

Inherent stability inside the flight envelope must be guaranteed in order to safely introduce
private and commercial UAV systems into the national airspace. The rejection of unknown …

Vision-based navigation is one of the most attractive research subjects on mobile robot
applications. An image-based navigation strategy was developed for a collaborative UAV …

Abstract Unmanned Aerial Vehicles (UAVs) are widely used in recent years for different
applications. Thus, UAV control attracted many researchers to suggest suitable controllers …
