About

Li Xu is a robotics and control systems researcher whose work spans biomechanically inspired actuation, autonomous robotic systems, and advanced control methodologies. His most recognized contribution lies in the study of Pneumatic Artificial Muscles (PAMs), where his 2009 work explored the mechanical modeling and actuation dynamics of these muscle-like actuators. PAMs offer compelling advantages — including high force-to-weight ratios, inherent compliance, and structural flexibility — making them particularly valuable for humanoid robotics, rehabilitation engineering, and prosthetic devices for individuals with disabilities. This foundational work has accumulated 12 citations, reflecting its relevance to researchers designing biologically inspired and assistive robotic systems. More recently, Xu has extended his expertise into autonomous vehicle testing and driving robot control, addressing the complex challenge of coordinating longitudinal and lateral vehicle manipulation. His 2021 work introduced a coupled dynamics model alongside fuzzy sliding mode and robust backstepping controllers to achieve precise, stable control while minimizing abrupt transitions between acceleration and braking. Together, these contributions demonstrate Xu's sustained commitment to bridging theoretical control design with practical robotic applications — from soft actuators in rehabilitation to intelligent autonomous systems in vehicular environments.
