Professor Oh-Min Kwon's research lab specializes in the analysis and control of uncertain dynamical systems, with a focus on time-delay systems, Markovian jump systems, and fuzzy modeling. The lab develops advanced stability criteria and filtering techniques using Lyapunov-based methods and linear matrix inequalities (LMIs), emphasizing robustness against parameter uncertainties and time-varying delays. Key research directions include finite-time performance analysis, passivity, and H∞ control in nonlinear and stochastic systems. The lab's work is highly application-oriented, addressing challenges in engineering systems with complex dynamics and uncertainties.

In this note, a new stabilization criterion for uncertain time-delay systems is proposed. Based on the Lyapunov method, the stabilization criterion is derived in terms of matrix inequalities which can be easily solved by efficient convex optimization algorithms. Numerical examples are included to show the effectiveness of the proposed method.
