About

Yew-Wen Liang is a leading researcher in nonlinear control systems, specializing in Takagi-Sugeno (T-S) fuzzy modeling and sliding mode control (SMC) techniques. His work bridges theoretical rigor with practical robotics applications, particularly in robust controller design for uncertain systems. Liang’s most influential contribution, "A Study of T–S Model-Based SMC Scheme With Application to Robot Control" (2008, 84 citations), pioneered the fusion of T-S fuzzy logic with SMC to stabilize second-order systems under parameter uncertainties and external disturbances. This approach significantly enhanced robustness and tracking precision in robot manipulators. In his related work, "Robust Control of the Robot Manipulator via an Improved Sliding Mode Scheme" (2007, 14 citations), he refined conventional SMC by introducing saturation-type laws, reducing chattering while maintaining disturbance rejection. Liang’s research has been widely cited for advancing intelligent control methodologies, offering scalable solutions for industrial automation and mechatronic systems. His work remains foundational for engineers developing resilient, adaptive controllers in complex environments.
