报告人简介：

Dr. Qi Liu is a Tenured Assistant Professor and PhD Supervisor in Mechanical Engineering at the University of Bath, UK, and a Research Affiliate of CIRP. He received his PhD from Harbin Institute of Technology with joint training at the University of Nottingham, followed by postdoctoral research at the University of Strathclyde. His research focuses on high-performance precision machining and smart manufacturing. He has led or participated in major projects such as EPSRC and NSFC key programmes, and has published over 40 papers in journals including the International Journal of Machine Tools and Manufacture (h-index 20).

报告内容简介：Industrial robots have become a vital component in smart manufacturing due to their high flexibility and low cost. However, their low structural stiffness often induces significant vibrations during machining, which severely limits their application in high-precision manufacturing. Existing control strategies are largely confined to specific robot poses or narrow frequency bands, making them inadequate in handling dynamic variations across the entire workspace. To address this issue, this study introduces an active vibration suppression technique based on H-infinity robust control. The approach employs external inertial actuators to apply real-time counteracting forces, and a highly robust controller is designed to accommodate model uncertainties caused by pose variations. Experiments conducted within a 500 mm × 500 mm work plane, including eccentric mass excitation and milling tests, demonstrate that the proposed H-infinity controller achieves remarkable vibration suppression under different pose conditions, reducing machining errors by up to 85%. It significantly outperforms conventional velocity feedback control. This research provides a reliable and stable control solution for large-scale high-precision robotic machining, offering substantial theoretical innovation and broad engineering applicability.
