Xiang Liu, Assistant Research Fellow, School of Ocean and Civil Engineering, Shanghai Jiao Tong University, won the 2023 Outstanding Paper Award for Young Scientists of COSPAR (Committee on Space Research).  This award, which will be presented at the COSPAR 2024 Scientific Assembly in Busan, South Korea, has been officially notified by COSPAR president Pascale Ehrenfreund in a letter signed on April 5.

The winning paper is “Nonlinear model order reduction and vibration control of a membrane antenna structure, Advance in Space Research, 2023, 71(12): 5369-5385.” Paper link: https://doi.org/10.1016/j.asr.2023.02.017. In this paper, a nonlinear model reduction method for large space membrane structures is proposed, and a novel nonlinear vibration control strategy by using cable actuators is proposed.  The research findings provide significant insights for the surface accuracy maintenance of large membrane spacecraft.
