About

Zhenghong Xu is a leading researcher in advanced robotics control, specializing in fault-tolerant and adaptive systems for robotic manipulators. His work addresses critical challenges in precision and safety, particularly under uncertainties and friction. Xu’s major contributions include developing an adaptive fault-tolerant control method that ensures stable operation even when manipulators experience failures, a breakthrough for industrial and service robotics. He further advanced the field by integrating extended state observers (ESO) with backstepping and nonsingular fast terminal sliding-mode control, achieving robust performance against model uncertainties and external disturbances. His innovative use of ESO-based backstepping sliding mode control to mitigate LuGre friction effects has set new standards for low-friction, high-precision manipulation. With over 49 citations across his most-cited papers, Xu’s work is widely recognized for its practical impact, offering scalable solutions for real-world robotic systems. His research not only enhances the reliability of autonomous manipulators but also provides a foundational framework for future studies in adaptive and fault-tolerant robotics.
