This book aims to present some advanced control methodologies for power
converters. Power electronic converters have become indispensable
devices for plenty of industrial applications over the last decades.
Composed by controllable power switches, they can be controlled by
effective strategies to achieve desirable transient response and
steady-state performance, to ensure the stability, reliability and
safety of the system. The most popular control strategy of power
converters is the linear proportional-integral-derivative series control
which is adopted as industry standard. However, when there exist
parameter changes, nonlinearities and load disturbances in the system,
the performance of the controller will be significantly degraded. To
overcome this problem, many advanced control methodologies and
techniques have been developed to improve the converter performance.
This book presents the research work on some advanced control
methodologies for several types of power converters, including
three-phase two-level AC/DC power converter, three-phase NPC AC/DC power
converter, and DC/DC buck converter. The effectiveness and advantage of
the proposed control strategies are verified via simulations and
experiments. The content of this book can be divided into two parts. The
first part focuses on disturbance observer-based control methods for
power converters under investigation. The second part investigates
intelligent control methods. These methodologies provide a framework for
controller design, observer design, stability and performance analysis
for the considered power converter systems.
