|讲座主题：Periodic Control of Power Electronic Converters
Zhou Keliang Senior Lecturer，University of Glasgow
Dr Yongheng YANG Assistant Professor, Aalborg University
A key issue for power electronic converters is the ability to tackle periodic signals in electrical power processing (e.g. synchronous frame transformation, sinusoidal voltage/current regulation, power harmonics mitigation, etc.) in such a way to precisely and flexibly convert electrical power. The Internal Model Principle (IMP) based periodic control has been found to provide power electronic converters with a superior control solution to the compensation of periodic signals with high accuracy, fast dynamic response, good robustness, and cost-effective implementation.
This seminar is to provide basic theory and some recent progress of IMP-based periodic control technology, complete analysis and synthesis of periodic control systems. It covers the control, compensation, and filtering of periodic signals in power electronic signal processing and proposes a unified framework for housing periodic control schemes for power converters, providing a perfect periodic control solution for power electronic conversion. This tutorial also consists of a number of demonstrative practical examples of the application of periodic control to: standalone/grid-connected PWM converters; CVCF High Frequency Link converters; shunt active power filters; and grid synchronizations.
This tutorial is intended for researchers/engineers in the field of power electronics and their applications, for control specialists exploring new applications of control theory in power electronics, and for advanced university students in these fields.
