About
Dr. Zhicheng Xie is a leading researcher in the control of space robotic systems, with a primary focus on the precise and safe manipulation of free-floating and free-flying space robotic manipulators (FSRMs and SRMs). Their work addresses the critical challenges of model uncertainty, external disturbances, and stringent state constraints inherent in orbital operations. Dr. Xie’s major contributions include pioneering a novel reinforcement learning-based adaptive sliding mode control scheme that significantly reduces chattering while ensuring robust motion control, as demonstrated in their most-cited 2020 paper (27 citations). They have further advanced the field by developing fixed-time and pre-defined time control strategies that guarantee convergence within a deterministic timeframe, independent of initial conditions—a crucial feature for time-critical space missions. Notably, their 2023 work introduced a barrier-Lyapunov-function-free approach to enforce full state constraints, enhancing safety without computational complexity. With a growing body of influential publications, including recent works on inverse optimal control (2025) and non-singular prescribed performance control (2026), Dr. Xie is recognized for pushing the boundaries of nonlinear control theory to enable more autonomous, reliable, and high-performance space robotics.
