About

Dr. Zhen-Guo Lee is a leading authority in precision motion control and servo drive systems, with a particular focus on vibration suppression in industrial automation. His most cited work, the 2006 paper "Vibration rejection scheme of servo drive system with adaptive notch filter," addresses a critical challenge in applications ranging from NC machine tools to robotics and factory automation. Dr. Lee's research targets the torsional vibrations that plague torque transmission in systems using Permanent Magnet Synchronous Motors (PMSM) coupled with ball-screws, gears, and timing belts. By developing an adaptive notch filter scheme, he provided a practical, real-time solution to reject mechanical resonances without requiring extensive system modeling. This contribution has garnered 23 citations, reflecting its foundational role in improving the stability and precision of servo-driven machinery. Dr. Lee's work bridges the gap between theoretical control algorithms and industrial implementation, making him a key figure in advancing the reliability of automated manufacturing systems. His research continues to influence engineers seeking to enhance performance in high-precision positioning and torque control applications.
