DESCRIPTION:Most engineering systems are open-loop stable. However\, in or
 der to cope with uncertainties and disturbances that widely exist in pract
 ice\, different feedback control strategies are adopted to achieve desired
  performance\, which makes feedback control one of the most fundamental co
 ncepts in control engineering. However\, feedback control could destabiliz
 e systems that are open-loop stable. In this talk\, a bounded controller t
 hat preserves the open-loop stability is presented at first. Then\, three 
 applications of the bounded controller are presented: 1) to equip synchron
 verters (power electronic converters that mimic conventional synchronous m
 achines) with guaranteed stability under normal and abnormal grid conditio
 ns\; 2) to limit the input current of three-phase PWM rectifiers\; 3) and 
 to achieve current-limiting droop control for parallel-operated inverters.
  These pave a way to solve the challenging problems of future power electr
 onics-enabled power systems in terms of stability and current-limiting cap
 ability.\n\nBiosketch:\nDr. Qing-Chang Zhong is the Max McGraw Endowed Cha
 ir Professor in Energy and Power Engineering at Dept. of Electrical and Co
 mputer Engineering\, Illinois Institute of Technology\, Chicago\, USA\, an
 d a Research Professor at the University of Sheffield\, UK. He is well rec
 ognized worldwide as one of the very few leading experts in both control a
 nd power electronics\, serving as a Distinguished Lecturer for the IEEE Co
 ntrol Systems Society and the IEEE Power Electronics Society. Before joini
 ng Illinois Institute of Technology\, he was the Chair Professor in Contro
 l and Systems Engineering at The University of Sheffield\, UK\, where he b
 uilt up a $5M+ research lab dedicated to the control of energy and power s
 ystems and attracted the support of Rolls-Royce\, National Instruments\, T
 exas Instruments\, Siemens\, ALSTOM\, Turbo Power Systems\, Chroma\, Yokag
 awa\, OPAL RT and other organizations. He obtained a PhD degree in 2000 fr
 om Shanghai Jiao-Tong University and another PhD degree in 2004 from Imper
 ial College London (awarded the Best Doctoral Thesis Prize). He (co-) auth
 ored three research monographs\, including Robust Control of Time-delay Sy
 stems (Springer\, 2006) and a No. 7 Amazon Best Seller Control of Power In
 verters in Renewable Energy and Smart Grid Integration (Wiley-IEEE Press\,
  2013). His fourth research monograph entitled Power Electronics-Enabled A
 utonomous Power Systems: Next Generation Smart Grids is scheduled for publ
 ication by Wiley-IEEE. He is an Associate Editor of four IEEE Transactions
  in control and power electronics\, including IEEE Trans. on Automatic Con
 trol\, IEEE Trans. on Control Systems Technology\, IEEE Trans. on Industri
 al Electronics\, and IEEE Trans. on Power Electronics. His current researc
 h focuses on advanced control theory and power electronics\, together with
  their applications in various industrial sectors.
