Manufacturing is one of the key pillars of a modern society. Many aspects of manufacturing center on the precision motion of the machines doing the material removal or addition. This talk will discuss advanced motion control schemes and their applications to manufacturing applications. In particular, we will motivate the use of high performing motion control schemes with precision manufacturing applications at the micro-scale. The key to high precision is the incorporation of feedforward information along with typical feedback algorithms. Iterative Learning Control (ILC) is a popular method to determine signal-based feedforward control. Two different additive fabrication techniques will be examined and the role of precision control highlighted. One is a micro-extrusion system used for tissue scaffold fabrication. Another is an electro-hydrodynamic Jet (orย e-Jet) printing that uses electric fields to drive ionic transport. After the demonstration of manufacturing processes, a brief introduction to Iterative Learning Control (ILC) will be given. ILC is a novel adaptive technique that allows us to learn repeated trajectories and maximize precision in the automation machinery used for fabrication. After an overview, the rest of the talk will discuss recent developments in ILC for both single axis and multi-axis systems. We demonstrate the benefits in performance with results in manufacturing applications.
