About

Wenxiang Deng is a leading researcher in nonlinear control systems, specializing in adaptive control, disturbance rejection, and robust output feedback techniques. His work addresses critical challenges in uncertain nonlinear systems, particularly those with time-varying delays, additive disturbances, and parametric uncertainties. Deng’s most influential contribution is the development of active disturbance rejection adaptive control, a framework that integrates adaptive laws with disturbance estimation to achieve high-performance tracking in the presence of unknown dynamics. This work, published in 2017, has garnered 173 citations, underscoring its impact on both theory and application. His subsequent research on time-varying input delay compensation for nonlinear systems, with 129 citations, introduced an output feedback approach that extends backstepping design to handle multiple-input, multiple-output systems under bounded disturbances. Deng has also advanced practical robotics, including adaptive control of hydraulic manipulators with gravity and friction identification, and robust control of cable-driven robots. His recent work on adaptive-gain disturbance estimators further refines asymptotic tracking for complex systems. Deng’s contributions bridge rigorous theory and real-world application, making him a key figure in modern control engineering.
