Chong‐Ho Choi

About

Chong-Ho Choi is a pioneering figure in robotics and control systems, whose work spans iterative learning control, bipedal locomotion, and construction automation. His most significant contributions lie in iterative learning control (ILC), where he developed foundational methods for nonlinear discrete-time systems and feedback systems, with his 1995 paper on ILC in feedback systems accumulating 152 citations. This work established convergence conditions that remain influential in adaptive control theory. In robotics, Choi advanced bipedal walking through trajectory generation and passive dynamic walking, notably demonstrating stable limit cycles for biped robots with symmetric fixed flat feet and knees—a hybrid system challenge that earned 50 citations for his 2007 trajectory generation method. His research also addressed practical automation, including a curtain wall installation robot tested on construction sites, reflecting his commitment to real-world applications. With over 260 total citations across his most-cited works, Choi’s legacy is defined by bridging theoretical rigor in control with tangible robotic systems, inspiring students and researchers in nonlinear control, hybrid dynamics, and field robotics.
