　　六、交流内容

　　Power converters which can precisely and efficiently convert, control and condition electricity, play a key role in the integration of various distributed generators, loads and transmission devices. However, in the processing of periodic dc or ac electricity, power converters will inject harmonic distortions to degrade the power quality and even the stability of power systems. To assure good power quality and stable power system operation, power converters highly demand optimal control strategies for compensating periodic signals with high accuracy, fast transient response, good robustness, and easy implementation. Simple but very effective internal model principle (IMP) based periodic controllers, such as integral control, resonant control, repetitive control, and so on, offer attractive control solutions to power converters.

　　This seminar will comprehensively present in‐depth IMP based periodic control technology for power converters, which will cover fundamental IMP as well as most recent frequency adaptive periodic control. Including analysis and synthesis of periodic control systems, it will present a general “PID” control solution to periodic signal compensation for power converters. Plenty of application examples will be provided.

　　七、主讲人简介

　　Keliang Zhou received his Ph.D. degree in Electrical and Electronics Engineering from Nanyang Technological University in Singapore in 2002. In 1992 and 1995 he was conferred the B. Eng. Degree and the M. Eng. Degree by Huazhong University of Science and Technology in China and Wuhan Transportation University in China respectively. He is currently a Senior Lecturer in the School of Engineering at the University of Glasgow in UK.

　　His current research is focused in the fields of power electronics and electric drives, control theory and applications, renewable energy and distributed generation, and smart grid technologies, which is dedicated to creating much better power electronic solutions to “smarter” and “greener” electrical power systems. Dr Zhou is one of pioneering researchers and active contributors in the fields of harmonic control (especially repetitive control) of power converters, PWM techniques, and modelling and control of high frequency link converters. He has published over 100 peer-reviewed technical articles (including about 50 leading journal ones) and tens of patents (including two key patented Leica technology on electronic levels).
