The implementation of passive damping is becoming a key knob for getting precision engineering applications to meet tighter specifications over time. In particular for high-tech systems, we see high-bandwidth control of systems that are classically designed for high reproducibility, i.e. based on masses and springs, becoming increasingly difficult. Despite the risk of hysteresis related virtual play, passive damping can highly simplify controller design and improve positioning performance.
This tutorial will address the design, modeling and implementation of passive damping in high-tech systems. We will discuss the trade off between damping on the one hand, and stiffness and position uncertainty on the other. Various passive damping principles will be discussed, viz. material damping (viscous-, linear viscoelastic- and composite damping), tuned mass- and robust mass damping, and constrained- and free-layer damping. We will focus on different application areas, such as medical equipment, machine tools and semiconductor applications.
