About
Zhengxiong Liu is a prominent researcher specializing in space robotics, tethered space systems, and advanced control theory, with particular expertise in on-orbit servicing, space debris removal, and robotic teleoperation. His work has garnered substantial recognition, accumulating over 900 citations across his most influential publications. Liu's foundational contributions center on tethered space robots (TSRs), where he has developed sophisticated impact dynamic models and adaptive control strategies for target capturing — a critical challenge in future on-orbit servicing missions. His widely cited 2018 review of space tether applications (165 citations) established a comprehensive framework for understanding emerging uses of tethered systems. Complementing this, his research on maneuverable tethered space net robots introduced innovative debris capture architectures that expanded the practical possibilities of active debris removal. Beyond tethered systems, Liu has made significant strides in robotic teleoperation, devising predictive control methods that address random time delays and sensorless force estimation — reducing reliance on costly hardware while maintaining operational precision. His more recent work on predefined-time control for teleoperation systems with input saturation demonstrates his continued push toward robust, real-world applicable solutions. Through adaptive control frameworks for post-capture attitude stabilization and distributed spacecraft control, Liu has meaningfully shaped the trajectory of space robotics research.
