Background
Background
Yi Cao is a Senior Lecture in the Department of Offshore, Process & Energy Engineering and the Course Director of Process Systems Engineering MSc. He obtained his MEng degree in Control Engineering from Zhejiang University in P. R. China in 1985 and his PhD degree in Engineering from the University of Exeter in 1996. His research interests are in advanced process control, including nonlinear system identification, nonlinear model predictive control, plantwide process control, self-optimising control and statistical process monitoring. He has published one monograph in Optimal Control Theory and Applications and over 100 refereed journal and conference research papers. One of these papers has been awarded as the best industrial application paper at the conference Control’96 by the journal of Control Engineering Practice in 1996.
Yi Cao was the main inventor of the patented technology, Inferential Slug Control (ISC), which received the East England Energy Group (EEEgr) Innovation Award in 2010. He successfully conducted a field trial on the ISC in North Sea in 2011. The field trial showed the ISC is able to increase oil production by 9.6% in addition to suppressing slugging.
