11-Active Vibration Isolation (Half-Day, In-person)
Dr. W.B.J. Hakvoort (University of Twente)
Monday, November 4, 2024 (1:30 PM – 5:30 PM)
High precision applications typically require isolation from floor vibrations and attenuation of vibrations induced by direct disturbances such as moving masses and cooling water turbulence. Passive vibration isolation requires a trade off in rejecting these two types of disturbances, while active vibration isolation does not suffer from this fundamental limitation.
This tutorial provides an introduction to active vibration isolation. First, the need for vibration isolation and the limitations of passive vibration isolation are discussed. This is continued by discussing several well-known active vibration isolation control strategies, their potential and limitations. An intuition of each strategy is given by the (fictitious) mechanical analogy. Basic tools for frequency domain performance analysis are explained in a 1 degree-of freedom (dof) setting, which enables the participant to design or select vibration isolation systems. Extensions to more advanced techniques are outlined and their potential is illustrated by experimental results.
The following topics are covered:
- Passive vibration isolation
- Frequency domain analysis tools
- Active vibration damping by positive position feedback
- Skyhook damping and related feedback vibration isolation methods
-Control synthesis from dynamic error budgeting - Disturbance feedforward control for vibration isolation
-Adaptive disturbance feedforward control
About the Instructor
Dr. Wouter Hakvoort received his MSc degree in Mechanical Engineering in 2004 and his PhD degree in 2019 from the University of Twente in the Netherlands. From 2008-2017 he was working with DEMCON Advanced Mechatronics in the Netherlands, where he was specialist in the control domain and had technical responsibility in research and development projects for high-tech mechatronic systems for industrial, precision and medical applications. In 2017 he joined the University of Twente, where he is currently Associate Professor. His research focus is on the integration of data and physics-based models for control, in particular (flexible) multibody modelling, adaptive control and iterative learning control for motion control, active vibration isolation control and control of forming processes. Application areas are in precision systems, mechatronics and robotics for the smart and high-tech industry. He has (co)authored over 16 peer reviewed journal articles, 5 conference articles and 31 conference contributions. He is associate editor for the journal of Precision Engineering.
