High-Speed Position and Motion Control at Extreme Resolution
Abstract: In this talk I will present research conducted in my laboratory, at The University of Newcastle, on ultrahigh-precision mechatronic system design for high-speed motion and position control applications. I will discuss the important role that piezoelectric sensors and actuators play in emerging motion control systems and opportunities that exist in this area. I will illustrate how the performance of a high-precision mechatronic system may be improved through proper integration of good electro-mechanical design, innovative interface electronics and advanced control systems. I will introduce a number of emerging applications, including high-speed nanopositioning, video-rate atomic force microscopy and on-chip scanning probe microscopy, and will discuss the associated challenges and opportunities in some detail.
Biography: Reza Moheimani joined The University of Newcastle in 1997, where he is currently a Professor of Electrical Engineering and an Australian Research Council Future Fellow. He is the founder and director of Laboratory for Dynamics and Control of Nanosystems, a multi-million-dollar state-of-the-art research facility. His current research interests are mainly in the area of ultrahigh-precision mechatronic systems, with particular emphasis on dynamics and control at the nanometre scale, including applications of control and estimation in nanopositioning systems for high-speed scanning probe microscopy, modelling and control of micro-cantilever based devices, control of micro-actuators in micro-electromechanical systems (MEMS) and control issues related to ultrahigh-density probe-based data storage systems.
Professor Moheimani is a Fellow of IEEE, a Fellow of IFAC and a Fellow of the Institute of Physics (UK). His research has been recognized by a number of international awards including: IFAC Nathaniel B. Nichols Medal (2014), IFAC Mechatronic Systems Award (2013), IEEE Control Systems Technology Award (2009) and IEEE Transactions on Control Systems Technology Outstanding Paper Award (2007). He has served on the editorial boards of a number of journals including IEEE/ASME Transactions on Mechatronics, IEEE Transactions on Control Systems Technology and Control Engineering Practice. He has chaired several international conferences and workshops, and currently chairs the IFAC Technical Committee on Mechatronic Systems.
