主题:Dynamics and Control of Piezo-driven High-precision Nano-positioning Systems

  主讲人:陕晋军教授,加拿大约克大学

交流内容Observations show that Earth''''''''s climate has been warming. To study climate change, many ground-based and space-based instruments have been developed to observe Earth''''''''s land, air, water and ice. An imaging Fabry-Perot spectrometer (FPS) has been developed at York University to obtain accurate, detailed, and collocated measurements of atmosphere and to retrieve simultaneously surface pressure, aerosol information, and surface albedo from the measurements. Multiple piezoelectric actuators are used in this instrument to achieve high-precision nano-positioning of optical system, therefore high-resolution spectrum. Dynamics modeling of nonlinearities and control system design are critical for this innovation instrument and have been developed in the past few years. This instrument has been validated through two successful stratospheric balloon flights in September 2016 and April 2017.

 

主讲人简介:

Prof. Jinjun Shan joined York University as an Assistant Professor of Space Engineering in July 2006. He was promoted to Associate Professor in July 2011, and Full Professor in July 2016. He currently serves as the Chair of Department of Earth and Space Science and Engineering, York University. Prior to his appointment at York University, he was a Post-Doctoral Fellow at University of Toronto Institute for Aerospace Studies from 2003 to 2016. He received his Ph.D. degree from Harbin Institute of Technology, China in 2002. Dr. Shan was awarded the Alexander von Humboldt (AvH) Fellowship, JSPS Invitation Fellowship, as well as Excellence in Teaching Award from York University. His current research interests are dynamics, control and navigation, smart materials and structures, and space instrumentation. He is the founding director of Spacecraft Dynamics Control and Navigation Laboratory (SDCNLab) at York University. Dr. Shan is also an Associate Editor for IEEE Transactions on Industrial Electronics, IEEE/ASME Transactions on Mechatronics and Journal of Franklin Institute.
