Altitude stabilization in unmanned vertical take-off/landing aircraft

IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014
Unmanned vertical take-off/Landing (UVTOL) Aircraft have received great attention for their flexibility and controllability in many applications requiring short range, low altitude air surveillance. Image acquisition and video recording from the air is useful for many demands. The operation of a UVTOL requires altitude stabilization with a very limited

The mathematical model of UAV vertical take-off and landing

Aircraft Engineering and Aerospace Technology, 2019
Purpose This paper aims to present a mathematical model of the dynamics of the unmanned aerial vehicle (UAV) vertical take-off and landing (VTOL). It will be used to develop control laws to a multirotor that is inherently unstable. Also, the model will be used to design algorithms to estimate the attitude of an object.

Tracking control of vertical taking‐off and landing vehicles with parametric uncertainty

International Journal of Adaptive Control and Signal Processing, 2020
SummaryThis paper considers the position and attitude tracking control of a quadrotor with inertia parameter uncertainty. With the aid of the cascade structure of the dynamics of the system, an immersion and invariance observer is proposed to estimate the unknown mass of the system first.

Development of adjustable landing struts for vertical take-off and landing vehicles

Proceedings of the Institution of Mechanical Engineers, Part E: Journal of Process Mechanical Engineering, 2022
For many Vertical Take-off and Landing vehicles, sloped landing surfaces have negative effects on their safety in the landing process. In this paper, a set of novel Adjustable Landing Struts containing actuators and absorbers are designed. The actuators can be used to change the attitudes of the landing struts relative to the fuselage of each Vertical ...

The Overview of Vertical Take-Off and Landing Technology

Applied and Computational Engineering
Vertical takeoff and landing (VTOL) technology is garnering significant attention in the aviation industry due to its distinct benefits and wide range of potential applications. A long runway is not necessary when using VTOL technology, which allows aircraft to take off and land vertically straight from the ground.

Cooperative Landing Control of Vertical Take Off and Landing Aircrafts on Oscillating Platform

2018 15th International Conference on Control, Automation, Robotics and Vision (ICARCV), 2018
This paper considers a cooperative landing problem of a group of planar vertical take off and landing (PV-TOL) aircrafts to be heterogeneous with uncertain parameters. Specifically, we focus on the situation that the landing platform is oscillating and establish a cooperative landing maneuver so that each aircraft can track the platform motion in a ...
