About

Ebrahim Samer El Youssef is a control systems researcher specializing in nonlinear and sliding mode control strategies for mobile robotics. His work focuses on developing robust tracking controllers for nonholonomic wheeled mobile robots, addressing the challenges of uncertainty and disturbance rejection in autonomous navigation. His most-cited paper, "PD-Super-Twisting Second Order Sliding Mode Tracking Control for a Nonholonomic Wheeled Mobile Robot" (2014), with 19 citations, introduces a novel combination of proportional-derivative control and super-twisting sliding mode algorithms to achieve precise trajectory tracking while mitigating chattering—a common issue in conventional sliding mode approaches. This contribution has influenced subsequent research in advanced motion control for wheeled robots, demonstrating practical applicability in real-world environments. El Youssef’s work bridges theoretical control design and robotic implementation, offering a foundation for students and researchers exploring robust, high-performance autonomous systems. His achievements highlight the importance of second-order sliding mode methods in enhancing stability and accuracy for nonholonomic platforms.
