About

Lilie Dewan is a control systems researcher whose work focuses on robust control strategies for nonlinear robotic systems, particularly rigid robot manipulators operating under uncertainty. Her most-cited paper, "A robust higher order sliding mode control of rigid robot manipulator" (2012), addresses the fundamental challenge of achieving reliable trajectory tracking in highly nonlinear robotic systems plagued by model uncertainties and external disturbances. In this work, Dewan advances sliding mode control theory by developing a higher-order sliding mode algorithm that ensures finite-time error convergence while mitigating the chattering phenomenon common in conventional sliding mode approaches. Although her citation count is modest at two, her contribution represents a technically rigorous solution to a persistent problem in robotic control—balancing robustness with smooth control action. Dewan's research sits at the intersection of nonlinear dynamics, Lyapunov stability theory, and practical robotic implementation, offering a mathematically grounded framework for engineers designing manipulators for precision tasks. Her work is particularly relevant for students and researchers exploring advanced variable structure control methods and their application to electromechanical systems requiring high reliability under uncertain operating conditions.
