报告题目：Vibration Suppression Approaches for Industrial Mechatronic Systems: Principle and Practice

报告摘要：

“Motion control” is a practical academic discipline grounded in modern control theory and widely applied to real-world “Mechatronic Systems” across diverse industrial fields. Fast-response and high-precision motion control is indispensable in advanced applications involving micro- and nano-scale positioning, such as data storage devices, machine tools, electronic component manufacturing equipment, and industrial robots, where high productivity, exceptional product quality, and cost efficiency are essential. In these systems, stringent motion performance requirements (e.g., fast response and settling, high trajectory and positioning accuracy) must be achieved while ensuring robustness and adaptability to disturbances, uncertainties/perturbations, and structural variations.

This E-Forum lecture will discuss how motion control technologies can be effectively applied to industrial mechatronic systems to meet these demanding performance objectives, with particular emphasis on mechanical vibration suppression. First, fundamental principles of vibration-suppression control will be introduced, including feedback controller design with notch filters that provide robustness against parameter variations in the resonant frequencies of multi-mass mechanical systems. Following to the fundamental design, a practical case study will be presented to demonstrate the precision motion control in an industrial robot manipulator. The case highlights the implementation of a variable notch filter, which dynamically adapts to changes in resonant frequencies caused by variations in the robot’s pose, thereby enhancing vibration suppression performance in practical operation.
