摘要:

As an enabling technology, power electronics is entering into all kind of energy processing systems and becomes fundamental to facilitate power conversions. As the “brain”, the control technology enables power electronic converters to precisely and flexibly convert and regulate the electrical power for the needs of different distributed generators, loads and transmission devices. A key issue for power electronic converters is the ability to tackle periodic signals in electrical power processing to assure good power quality and even system stability, such as synchronous frame transformation, sinusoidal voltage/current regulation, power harmonics mitigation, and so on. 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 present basic theory and some recent progress of a unified IMP-based periodic control technology, which refers to a family of control algorithms that incorporate a periodic signal model to enable perfect control, compensation and filtering of periodic signals, e.g., resonant control, various selective harmonic control, repetitive control, and periodic signal filtering.  It proposes a unified approach to the analysis and synthesis of periodic controllers in discrete-time domain, which covers the general internal model of periodic signals, general stability criteria for digital periodic systems, and optimal gain tuning strategy. 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.As an emerging topic, the periodic control has the great potential to be one of the best control solutions for power converters but not limited to, and to be a standard industrial controller like the PID control.
