About

Dong Sang Yoo is a robotics researcher whose work centers on the control of complex mechanical systems, particularly robot manipulators and underactuated mobile robots. His major contributions lie in the development and real-time implementation of advanced dynamic control algorithms, with a strong emphasis on sliding mode control (SMC) and integral sliding mode control (ISMC). Yoo’s research addresses critical challenges in robotics, such as robust stabilization on slopes and handling uncertain nonlinearities in robot dynamics. His most cited work, "Real-time implementation and evaluation of dynamic control algorithms for industrial manipulators" (1991, 14 citations), demonstrated the practical feasibility of these algorithms. He further advanced the field by proposing an integral sliding mode control with adaptive boundary estimation for uncertain parameters, and by comparing SMC and ISMC for set-point regulation and trajectory tracking. Yoo also tackled the challenging control of a two-wheeled inverted pendulum mobile robot on uniform slopes, and applied sliding mode techniques to the pendubot, an underactuated system. His cumulative work, spanning over two decades, has earned him recognition for bridging theoretical control design with real-world robotic applications, making his research valuable for students and engineers working on robust robot control.
