Universal Extremum Seeking Mechanism for Lift Variation in Soaring Birds Flight: A New Paradigm in Computational Physics and Biology
Simone Martini, Dipesh Kunwar, Sameh A. Eisa
In this letter, we reveal a universal, very simple extremum seeking natural feedback law and mechanism that governs, adapts, and generates in real-time, optimized lift variations f…
Nonsmooth High-Order Averaging Theory with Application to Extremum Seeking Optimization and Control
Hesham Abdelfattah, Sameh A. Eisa, Peter Stechlinski
In this paper, we introduce a higher-order averaging theory and method for a wide range of nonsmooth systems that are generally characterized by the classical averaging canonical f…
Extremum seeking with exponential convergence via high-order Lie bracket approximations
Victoria Grushkovskaya, Sameh A. Eisa
This paper focuses on the further development of the Lie bracket approximation approach for optimization and control via extremum seeking systems. Classical results in this area pr…
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…
