Analysis and Design of Nonlinear Systems in the Frequency Domain

Dr. Yunpeng Zhu received his B.S. and M.S. degrees in Mechanical Engineering and Automation in 2013 and 2015, respectively, from Northeastern University, China. In 2020, he received a PhD in Automatic Control and Systems Engineering, which was fully supported by a scholarship of the Faculty of Engineering at Sheffield University. He is currently a Research Associate working on a £1.6 million UK EPSRC project led by Prof Z Q Lang, at the University of Sheffield and involving 3 other UK universities and 6 industry partners.

From 2013 to 2020, he has published over 30 international journal papers and 10 conference papers, including some very top journals in the subject area of systems and control including Automatica and IEEE Transactions on Control Systems Technology. He has acted as a referee for over 10 high quality journals including Automatica, IEEE transactions on Automatic Control, IEEE transactions on Mechatronics, Mechanical Systems and Signal Processing, and Nonlinear Dynamics.
