About

Cheng-Huei Han is a researcher specializing in robotics, precision motion control, and vibration suppression. His work focuses on improving the performance of robotic manipulators and harmonic drives—critical components in high-precision systems. Han’s major contribution lies in developing innovative control strategies to mitigate transmission errors in harmonic drives, which cause speed ripple and vibration. His 2008 paper on using a peak filter with acceleration feedback to suppress vibration due to transmission error has garnered 26 citations, reflecting its impact on the field. This work is notable for addressing a persistent challenge in robotics and precision positioning, where near-zero backlash and high reduction ratios are essential. Han also explored sensor-based controller tuning for robot manipulators through real-time optimization, as seen in his 2009 study. While his citation count is modest, his contributions are valued for their practical relevance in enhancing the accuracy and reliability of robotic systems. Han’s research continues to influence engineers and researchers working on advanced motion control and vibration damping in precision machinery.
