About

Wenquan Gong is a control systems researcher whose work focuses on the advanced trajectory tracking of wheeled mobile robots (WMRs) under external disturbances. His primary research areas include finite-time and fixed-time control theory, sliding mode control, and disturbance observer design for nonlinear robotic systems. Gong’s major contributions lie in developing robust control strategies that ensure precise and rapid convergence of WMRs to desired paths, even in the presence of unknown perturbations. In his most-cited work, "Finite-time Trajectory Tracking Control of A Wheel Mobile Robot based on Integral Terminal Sliding Mode" (2020, 3 citations), he introduced a finite-time disturbance observer using the smooth tanh(·) function to estimate and compensate for external disturbances, enabling faster and more accurate tracking. He further advanced this line of inquiry in "Fixed-time Trajectory Tracking Control of a Wheeled Mobile Robot" (2021, 2 citations), where he decomposed the robot’s dynamic error system into separate attitude and position subsystems, achieving convergence within a fixed time independent of initial conditions. Though his citation counts are modest, Gong’s work is notable for its theoretical rigor and practical relevance to autonomous mobile robotics, offering valuable insights for students and researchers interested in nonlinear control and disturbance rejection.
