About
Leonardo Acho is a control systems researcher whose work centers on nonlinear control theory, robust control design, and the dynamics of mechanical systems—particularly robotic manipulators. His most influential contributions address the challenging problem of friction in mechanical systems, developing sophisticated control strategies to overcome its destabilizing effects. His 2003 paper on nonlinear H∞-control of nonsmooth time-varying systems, with 54 citations, established foundational methods for managing friction in robotic manipulators, while a companion paper on switched chattering control garnered an additional 37 citations, together demonstrating his dual command of both analytical and algorithmic approaches. Acho has made significant advances in underactuated systems, particularly through his Model Orbit Robust Stabilization (MORS) framework applied to the Pendubot—a notoriously difficult two-link pendulum robot—producing multiple cited works on swing-up and orbital stabilization using quasi-homogeneous and variable structure methods. His research extends into adaptive friction compensation, velocity estimation for mechanical systems, and neural network-enhanced variable structure control. His 2020 work on the Furuta pendulum under time-delay and exogenous perturbation reflects his continued relevance in experimental robust control. Across his career, Acho has bridged rigorous mathematical theory with real-world experimental validation, making his work valuable to researchers tackling nonlinear and uncertain dynamical systems.
