About

Yuanfei Xu is a robotics researcher whose work bridges practical mobile robotics and advanced space manipulator control. His most-cited paper, "Grid Line Tracking Omnidirectional Robot Based on Visible Light Sensor and Mecanum Wheel PID Control" (2021, 4 citations), showcases his expertise in mechatronic system design—integrating STM32 microprocessors, PWM-driven DC motors, and closed-loop PID control to achieve precise omnidirectional motion. This work demonstrates a strong foundation in real-time embedded control and sensor-based navigation. Xu's more recent contribution, "Singular perturbation-based pose tracking control for rigid-flexible coupled space robot" (2025, 1 citation), marks a significant leap into aerospace robotics. Addressing the challenge of controlling space robots with both rigid and flexible components under parameter uncertainty and external disturbances, he developed a novel composite controller combining sliding-mode and linear quadratic regulator (LQR) techniques. By applying singular perturbation theory, he elegantly decoupled the system into slow (rigid motion) and fast (vibration) subsystems, then designed an adaptive sliding-mode controller with radial basis function neural networks for the former and an optimal LQR for the latter. This work highlights his ability to tackle complex, multi-timescale dynamics with theoretical rigor and practical control design.
