About

Shih-Hsiung Twu is a pioneering figure in the field of variable structure systems (VSS) control, with a focused research career dedicated to solving one of the most persistent challenges in sliding-mode control: chattering. His most influential work, the 1990 paper "Adaptive chattering alleviation of variable structure systems control," which has garnered 71 citations, introduced a groundbreaking two-phase adaptive control algorithm. This method first minimizes the time required to reach the switching surface, then actively alleviates the high-frequency chattering that degrades system performance and causes wear. Twu’s earlier foundational work in 1988 further refined these concepts for a specific class of nonlinear systems, demonstrating through simulation the practical viability of his chattering-alleviation techniques. His contributions have had a lasting impact on the robustness and applicability of VSS control in real-world engineering systems, making his research essential reading for students and engineers working on adaptive and nonlinear control.
