About

Dr. Zhang Zheng is a leading roboticist whose research centers on the dynamic modeling, control, and stabilization of nonlinear, underactuated systems—most prominently, two-wheeled self-balancing robots. His major contributions lie in tackling the fundamental challenges of these high-order, unstable platforms, which are characterized by heavy coupling and inherent instability. Dr. Zheng pioneered the application of Newtonian dynamics to derive precise linearized models near equilibrium points, enabling effective state feedback control. He further advanced the field by designing and implementing robust variable structure sliding mode controllers, which employ a switching function on the sliding surface to achieve superior balance and trajectory tracking. This work, published in 2016, has garnered over 22 citations, demonstrating its foundational impact on mobile robotics. By providing practical, implementable control solutions for two-wheeled robots, Dr. Zheng’s research has direct implications for the development of agile, self-balancing personal transport vehicles and autonomous service robots, marking him as a key innovator in the domain of intelligent motion control.
