About
Yicheng Liu is a leading researcher in the field of space robotics, with a primary focus on the trajectory planning and robust control of dual-arm free-floating space robots (FFSRs). His work addresses critical challenges in autonomous space operations, including high-precision trajectory tracking, self-collision avoidance, and the elimination of tracking errors without expending valuable fuel. Liu’s major contributions include the development of novel, high-performance control strategies such as a general nonsingular predefined-time terminal sliding mode control and a fixed-time nonsingular terminal sliding mode control, which achieve rapid, chattering-free stabilization even under large initial errors and bounded uncertainties. His most-cited paper (65 citations) on predefined-time sliding mode control, along with his work on fixed-time control (56 citations), has set new standards for speed and robustness in space robot manipulation. Liu has also innovated in trajectory planning, integrating pose feedback and evolutionary algorithms to ensure smoother joint paths and safer obstacle avoidance. His research, consistently published in top venues, is instrumental in advancing the autonomy and reliability of next-generation space robots for complex tasks like satellite servicing and assembly.
