"Title:Piezo-driven Nano-positioning System and Its Application to an Imaging Fabry-Perot Spectrometer"
Abstract
Piezoelectric actuators have many advantages such as high resolution, fast response, large bandwidth, and good temperature stability. They have been used in a wide range of industrial applications to realize high precise motion. However, the piezoelectric actuators inherently have their own nonlinear behaviour such as hysteresis, creep, thermal drift and vibration which deteriorates overall performances including stability of the developed systems. In this talk, Prof. Shan will present his work on dynamics modeling and compensation for the nonlinearities of the piezoelectric actuators, as well as its application to an imaging Fabry-Peort spectrometer for atmospheric studies.

Professor Wen received his Bachelor of Science degree from the Department of Mechanical Engineering at the National Taiwan University in 1986 and Master of Science and PhD from the Department of Aeronautics at the California Institute of Technology (Caltech), U.S.A. in 1989 and 1994 respectively. He worked at Caltech as a Research Fellow from February 1994 to July 1994 and then continued his teaching and research works at the Department of Mechanical Engineering at the Da-Yeh University, Taiwan. He was promoted to full professorship in February 2002. He had been the Chairman of the Department of Mechanical and Vehicle Engineering from August 1997 to July 2000, and the Provost from August 2004 to July 2006 in the Da-Yeh University, Taiwan. In August 2006, Professor Wen joined the Department of Aeronautics and Astronautics of the National Cheng Kung University (NCKU), Taiwan, before joining the Department of Mechanical Engineering, The Hong Kong Polytechnic University in 2012 as professor. While serving in HKPolyU, he has been the associate head (research) of ME department and the interim head of AAE from 2015 to 2019 and from 2019 to 2021, respectively. He is currently serving as the head of AAE. Professor Wen has authored and co-authored more than 300 scientific papers, conference papers and book chapters. He was also awarded 15 patents. His current research interests are in the areas of (1) Technology development of UAVs and MAVs; (2)Hypersonic/Supersonic aerothermodynamics; (3) Shock/Droplet and Shock/Bubble Interactions; (4) Detonation; (5) Flow Control by plasma actuators; and (6) Urban Environment Simulation. Professor Wen, served as associate editor of the prestigious international journal—AIAA Journal and the vice chair of the technical committee of fluid mechanics, ASME. He is currently an HKIE Fellow and AIAA Associate Fellow and editor of Shock Waves Journal, and Advanced in Aerodynamics. He is also a member of, various key professional boards and bodies related to the Aerospace Engineering.
