About

Zhao-Qin Guo is a leading researcher in nonlinear control theory and biomimetic robotics, with a focus on the stabilization and motion control of underactuated systems. His most influential work centers on the two-wheeled mobile robot (2WMR), an inherently unstable inverted-pendulum platform. In a landmark 2013 paper (316 citations), Guo pioneered the first implementation of integral sliding-mode control (ISMC) on a 2WMR, achieving robust position control despite model uncertainties and external disturbances. He further advanced this domain with a Takagi–Sugeno-type fuzzy logic controller (2012, 115 citations), demonstrating how intelligent control can stabilize complex, nonlinear dynamics. Beyond wheeled robots, Guo has made significant contributions to biomimetic underwater robotics. He developed a general internal model (GIM) learning framework that enables multi-joint robotic fish to replicate live fish locomotion from observational data, and designed sliding-mode controllers to resist parameter uncertainties in carangiform robots. His work on pectoral fin-assisted motion control further enhances maneuverability. With over 440 citations across his top papers, Guo’s research bridges robust control theory and bio-inspired design, offering practical solutions for autonomous systems ranging from mobile robots to aquatic vehicles.
