About
Dong-Soo Choi is a researcher whose work spans optimal control theory, robotics, and aerospace actuation systems. His most significant contributions lie in the mathematical foundations of time-optimal control, particularly for state-constrained systems. His 2005 paper on comparison principles for state-constrained differential inequalities — his most cited work with 15 citations — established a rigorous framework characterizing maximal solutions through set-valued analysis, providing tools with broad applicability in control engineering. Building on this theoretical foundation, his 2002 research demonstrated that time-optimal control of state-constrained second-order systems could be precisely characterized through forward and backward velocity limitation curves, with direct application to robotic manipulators. That same year, he introduced a computationally efficient approximation method for time-optimal path control in robotics, addressing practical implementation challenges that had limited real-world deployment of optimal control strategies. Beyond theoretical contributions, Choi has also engaged in applied engineering, contributing to the development of 100Nm-class Control Moment Gyroscopes for industrial applications in aerospace, maritime, and robotics domains. His body of work reflects a researcher comfortable bridging rigorous mathematical theory and practical engineering challenges across multiple disciplines.
