Rui Zhang 张睿

I am currently a Ph.D. candidate in Applied Control and Computing Laboratory of Department of Mechanical and Automation Engineering, The Chinese University of Hong Kong (CUHK), supervised by Prof. Jie Huang. I received a B.E. degree in Flight Vehicle Design and Engineering, and an M.E. degree in Aerospace Science and Technology from Beihang University (aka. Beijing University of Aeronautics and Astronautics, BUAA) in 2017 and 2020 respectively. I was awarded the National Scholarship in BUAA and the Vice-Chancellor's PhD Scholarship in CUHK.

My research interests include multi-agent systems, nonlinear control, output regulation, adaptive control, robot manipulator control, spacecraft guidance, navigation, and control.

This paper proposes an event-triggered implementation of the output-based adaptive distributed observer for a linear leader system over jointly connected communication networks. The proposed triggering mechanism not only retains the exponential convergence property of the analog adaptive distributed observer but also prevents the Zeno phenomenon from happening.

This Note investigates the feasibility of using a high-precision spaceborne accelerometer for orbit determination of LEO satellites in low-altitude regime where the atmospheric drag is prominent.

Multiple AEOSs scheduling model for oversubscribed targets with multiple observations is initially developed, and the potential observation missions attained by available time windows discretization are regarded as nodes in the complex networks.

The Three Dimensional Magnetically Suspended Wheel (3-DMSW) is applied in attitude control. The saturation of rotor shaft deflection angle and rotor's variable rotational speed isconsidered. A novel anti-saturation steering law for 3-DMSW cluster is proposed. A new weight adjustment method for the steering law is specially designedand demonstrated theoretically.

An autonomous low-Earth orbit determination method based on measurements of atmospheric drag is proposed, with use of a high-precision tri-axis accelerometer as well as a star sensor.

The influence of the initial orbit states and the J2 perturbation on the fuel consumption is analyzed through multiple numerical simulations. The results show that the optimization method is effective and the influence on the fuel consumption provide some valuable engineering guidance.

I am interested in photography, poetry and hiking. I am a talented violinist, too. Here are some of my photos.
