About

Sang Jae Lee is a robotics researcher whose work focuses on trajectory tracking and motion control for mobile robotic systems, particularly two-wheeled mobile robots with nonholonomic constraints. His key contributions lie in developing advanced control strategies that combine sliding-mode control with fuzzy logic and hyperbolic functions to achieve robust and precise trajectory tracking. Lee's most-cited paper, "Trajectory Tracking Control for Two Wheeled Mobile Robot using Fuzzy Sliding Mode Control based Hyperbolic Function" (2014), introduces a novel controller architecture that separates attitude and position control, effectively addressing the challenges of nonlinear dynamics and external disturbances in wheeled mobile robots. While his citation count remains modest, his work represents an important step in integrating fuzzy logic with sliding-mode techniques to reduce chattering and improve tracking accuracy. Lee's research is particularly relevant for applications in autonomous navigation, service robotics, and industrial automation, where reliable motion control is essential. His approach offers a practical solution for real-time implementation, making his work a valuable reference for students and researchers exploring robust control methods in mobile robotics.
