First Experimental Demonstration of Natural Hovering Extremum Seeking: A New Paradigm in Flapping Flight Physics
Ahmed A. Elgohary, Rohan Palanikumar, Simone Martini +1
In this letter, we report the first experimental demonstration of the recently emerged new paradigm in hovering and flapping flight physics called (Natural Hovering Extremum Seekin…
Model-Free Optimization and Control of Rigid Body Dynamics: An Extremum Seeking for Vibrational Stabilization Approach
Rohan Palanikumar, Ahmed A. Elgohary, Simone Martini +1
In this paper, we introduce a model-free, real-time, dynamic optimization and control method for a class of rigid body dynamics. Our method is based on a recent extremum seeking co…
Model-free source seeking of exponentially convergent unicycle: theoretical and robotic experimental results
Rohan Palanikumar, Ahmed A. Elgohary, Victoria Grushkovskaya +1
This paper introduces a novel model-free, real-time unicycle-based source seeking design. This design autonomously steers the unicycle dynamic system towards the extremum point of…
Hovering Flight in Flapping Insects and Hummingbirds: A Natural Real-Time and Stable Extremum Seeking Feedback System
Ahmed A. Elgohary, Sameh A. Eisa
In this paper, we take an initial and novel step toward characterizing the physics of the hovering phenomenon in flapping insects and hummingbirds as a new class of extremum seekin…
Model-Free and Real-Time Unicycle-Based Source Seeking with Differential Wheeled Robotic Experiments
Ahmed A. Elgohary, Sameh A. Eisa, Shivam Bajpai
Many autonomous robots aimed at source-seeking are studied, and their controls designed, using unicycle modeling and formulation. This is true not only for model-based controllers,…
Investigating the Performance of EKF, UKF, and PF for Quadrotor Position Estimation in Hurricane Wind Disturbances
Ahmed A. Elgohary, Benjamin Gwinnell, Josh Augustine
Natural disasters, such as hurricanes and typhoons, pose significant challenges to public safety and infrastructure. While government agencies rely on multi million dollar UAV syst…
