Digital printing and imaging systems are well-recognized mechatronics devices. They are an integral part of our daily life. Although the traditional print media has been in decline, the recent interest in using printing as a scalable fabrication process has renewed the interest in printing. In addition to deposit precisely controlled amount of colorant with the necessary spatial accuracy, the interaction between the colorant and the substrate and the colorant with themselves all contribute to the quality of the image. In this talk, we will discuss modeling and control approaches that were motivated to reduce spatial artifacts in printing and imaging processes as well as insights gained when implementing these control approaches with computation and resource constraints.

George Chiu is a Professor in the School of Mechanical Engineering with courtesy appointments in the School of Electrical and Computer Engineering and the Department of Psychological Sciences at Purdue University. Dr. Chiu received the B.S. degree in Mechanical Engineering from the National Taiwan University in 1985 and the M.S. and Ph.D. degrees from the University of California at Berkeley, in 1990 and 1994, respectively. Before joining Purdue in 1996, he worked for the Hewlett-Packard Company, designing inkjet printer and multi-function devices. From September 2011 to June 2014, he served as the Program Director for the Control Systems Program in the Engineering Directorate of the National Science Foundation. Dr. Chiu's current research interests are mechatronics and dynamic systems and control with applications to digital printing and imaging systems, digital fabrications, human motor control and robotics, motion and vibration perception and control. He received the 2012 NSF Director’s Collaboration Award, the 2010 IEEE Transactions on Control System Technology Outstanding Paper Award and the Purdue University College of Engineering 2010 Faculty Engagement/Service Award.  Professor Chiu is the Editor-in-Chief for the IEEE/ASME Transactions on Mechatronics. He served on the Executive Committee of the ASME Dynamical Systems and Control Division from 2007 to 2015. He is a Fellow of ASME and the Society for Imaging Science and Technology (IS&T) and a senior member of IEEE.
