Trajectory tracking of a quadrotor using extend state observer based U-model enhanced double sliding mode control (2023)
Journal Article

This paper develops a novel U-model enhanced double sliding mode controller (UDSMC) for a quadrotor based on multiple-input and multiple-output extended-state-observer (MIMO-ESO). UDSMC is designed using Lyapunov synthesis and Hurwitz stability to no...

A new configuration of composite nonlinear feedback control for nonlinear systems with input saturation (2022)
Journal Article

This study proposes a U-control–based Composite Nonlinear Feedback (U-CNF) design procedure. This U-CNF control establishes a double feedback loop framework for generalisation and simplification in designing the CNF control systems. Two controllers,...

Event-triggered based state estimation for autonomous operation of an aerial robotic vehicle (2019)
Presentation / Conference Contribution

In this article the problem of event-triggered (ET) state estimation for autonomous navigation of an aerial vehicle is investigated numerically. The aerial vehicle is considered as a general example of a nonlinear non-Gaussian system for state estima...

Fast, vision-based, line-following schemes for Micro Aerial Vehicles in nuclear environments (2019)
Presentation / Conference Contribution

Many nuclear power plants are reaching the end of their economic lifetime and the decommissioning of legacy nuclear facilities is an important challenge in the next few decades. Since the radiation level in these facilities is significant, autonomous... Read More about Fast, vision-based, line-following schemes for Micro Aerial Vehicles in nuclear environments.

Robust Intelligent Control of Underactuated Ground- based and Aerial Robots with Matched/Mismatched Uncertainties and Disturbances (2019)
Presentation / Conference Contribution

Recently, inspired by nature, the evolution of novel materials and fabrication procedures for the design and control of soft-bodied robots have led to deformable actuators that are versatile, power-efficient, compliant, agile, self-healing and intell...
