About

Sebastian Alejandro Godoy is a control systems researcher whose work centers on trajectory tracking, mobile robotics, and underactuated marine vessels. His most influential contribution, "Trajectory Tracking of Underactuated Surface Vessels: A Linear Algebra Approach" (2013), has garnered over 120 citations and stands as a landmark study in applying linear algebra-based control methods — originally developed for robotic systems — to the complex dynamics of underactuated ships navigating the x-y plane. This foundational work sparked a productive research thread that Godoy has extended across multiple platforms and scenarios. Throughout his career, Godoy has consistently tackled one of robotics' most practical challenges: designing controllers that respect real-world velocity and actuation constraints while still guaranteeing zero convergence of tracking errors. His papers from 2014 through 2019 progressively refine this agenda, incorporating numerical approximation techniques, interpolation-based methods, parameter regulation strategies, and uncertainty estimation to make trajectory tracking controllers more robust and deployable. His 2019 work on additive uncertainties estimation reflects a mature, systems-oriented perspective on robustness in mobile robot control. Godoy's cumulative body of work demonstrates a disciplined focus on bridging theoretical control design with practical engineering constraints, making his research particularly valuable to students and practitioners working in autonomous vehicles, marine robotics, and nonlinear control systems.
