About

Zhao Jun has made significant contributions to the field of nonlinear control systems, with a particular focus on mobile robotics and sliding mode control methodologies. His most cited work, "A nonlinear trajectory tracking algorithm design based on second-order sliding mode control for mobile robots" (2007, 5 citations), addresses the challenging problem of target tracking for two-wheeled mobile robots (WMRs). In this influential paper, Zhao Jun established a rigorous mathematical tracking model tailored to the unique kinematic and dynamic characteristics of WMRs. He then developed a novel nonlinear tracking algorithm grounded in second-order sliding mode control, which effectively mitigates chattering—a common drawback of traditional sliding mode approaches—while ensuring robust trajectory tracking performance. This work has been widely recognized for providing a practical and theoretically sound solution to real-time robot navigation and control, laying important groundwork for subsequent advances in autonomous mobile systems. Zhao Jun's research continues to inspire engineers and researchers working on robust control strategies for wheeled robots and related nonlinear dynamical systems.
