In this article, we introduce an adaptive strictly negative-imaginary (SNI) autopilot for a low-
cost quadrotor aerial vehicle, specifically designed to achieve high precision hovering and …

To address the challenge of maintaining high robustness of target tracking in a 3D dynamic
high-altitude scenario, this paper presents a method to formulate continuous strategic …

A novel data-driven robust approximate optimal Maximum Power Point Tracking (MPPT)
control method is proposed for the wind power generation system by using the adaptive …

In this article, a hybrid algorithm of Levenberg-Marquardt (LM) and proportional-integral-
derivative neural network (PIDNN) with the relay feedback (LM-PIDNN-RF) is proposed to …

This letter addresses the design of a global saturated trajectory tracking controller for a
quadcopter in the presence of external disturbances. The proposed control law guarantees …

In this paper, we focus on the transition control of a ducted fan vertical take-off and landing
(VTOL) unmanned aerial vehicle (UAV). To achieve a steady transition from hover to high …

Robustness in the face of uncertainties is an integral part of designing a real-time control
system. Based on negative imaginary (NI) systems theory, we design robust and adaptive …

In this article, we address the task of cooperative path following control of multiple
autonomous quadcopters in the presence of unknown external disturbances. Under the …

This study presents a multilayer interval type-2 fuzzy controller for controlling quadcopter
unmanned aerial vehicles, and its main contribution is the design of a multilayer structure in …

Abstract Unmanned Aerial Vehicle (UAV), especially fixed wing, are widely used to carry out
various missions, namely civil and military missions. To support the implementation of this …
