Research Interests

Qing-Chang Zhong, an IEEE Fellow and an IET Fellow, holds the Max McGraw Endowed Chair Professor in Energy and Power Engineering and Management at Illinois Institute of Technology, µç³µÎÞÂë, USA. He was educated at Imperial College London (Ph.D., 2004, awarded the Best Doctoral Thesis Prize), Shanghai Jiao Tong University (Ph.D., 2000), Hunan University (MSc, 1997), and Hunan Institute of Engineering (Diploma, 1990).

Zhong is well recognized worldwide as one of very few leading experts in control, power electronics and power systems, being appointed as a Distinguished Lecturer of three IEEE Societies (Control Systems/Power Electronics/Power and Energy), and an Associate Editor of seven flagship journals in control and power electronics, including IEEE Trans. on Automatic Control, IEEE Transactions on Control Systems Technology, IEEE Trans. on Power Electronics and IEEE Trans. on Industrial Electronics. He is also truly globalized, having previously held positions in the UK, Israel and China. Before joining Illinois Institute of Technology, he was the Chair Professor in Control and Systems Engineering at The University of Sheffield, UK, where he built up a $5M+ research lab dedicated to the control of energy and power systems and attracted the support of Rolls-Royce, National Instruments, Texas Instruments, Siemens, ALSTOM, Turbo Power Systems, Chroma, Yokogawa, OPAL RT etc.

Zhong is a dedicated educator. Two of his four graduated Chinese Ph.D. students received the National Award for Outstanding Chinese Students Abroad including one Grand Prize (only 10 such awards worldwide each year and only two UK students have received the Grand Prize so far). Ten of his researchers have secured faculty positions.

Zhong’s current research focuses on advanced control theory, power electronics and the seamless integration of both to address fundamental challenges in various energy and power systems. In 2016 alone, he had 30 journal papers accepted/published, including 20 papers in IEEE Transactions. In total, he has published 200+ papers. He (co-)authored three research monographs, including Control of Power Inverters in Renewable Energy and Smart Grid Integration (Wiley-IEEE Press, 2013) and Robust Control of Time-delay Systems (Springer, 2006). He solved a series of fundamental theoretical problems about robust control of time-delay systems. He is the lead inventor of virtual synchronous machines (synchronverters) and proposed the architecture, together with two technical routes, for next-generation smart grids based on the synchronization mechanism of synchronous machines. This unifies the interface of all different players --- such as wind turbines, solar panels, electric vehicles, energy storage systems and the majority of loads --- with the grid so that they can play the same role as conventional power plants to maintain system stability, enhance system resiliency, and reduce the chance of large-scale blackouts.

He served as a Senior Research Fellow of the Royal Academy of Engineering/Leverhulme Trust, UK, the UK Representative to the European Control Association, a member of the Scientific Advisory Board of US NSF FREEDM Systems Center at North Carolina State University and the Rolls-Royce UTP Board in Power Electronics Systems. He also served as grant reviewer for funding bodies from the UK, China, Singapore, Finland, Kuwait, Italy, Netherlands, Israel, and other countries.
