Piezo-driven Nano-positioning System and Its Application to an Imaging Fabry-Perot Spectrometer
Prof. Jinjun Shan
Department of Earth and Space Science and Engineering, York University
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.
Bio of Prof. Jinjun Shan:
Prof. Jinjun Shan is a Full Professor at the Department of Earth and Space Science and Engineering, York University. He joined York University in 2006 as Assistant Professor of Space Engineering and was promoted to Full Professor in 2016, he also served as the department chair in 2018-2023. Prof. Shan’s research areas include dynamics, control and navigation of autonomous systems, multi-agent systems, smart materials and structures, spacecraft dynamics and control, and space instrumentation.
