As the demand for environmental protection and energy conservation increases, electric motors have become the most important mechanical driving force.
Many mechanical systems that used classic diesel or gasoline engines, hydraulics, etc. are now being replaced by environmentally friendly and easy-to-control electric drive systems.
Today, electric motor drive systems play a vital role in supporting the convenience of our lives, from home appliances and office equipment to transportation and industrial equipment.
The main purpose of this book is to provide motor control technology for stable and efficient control of these systems.

Representative electric motors widely used today include DC motors, AC motors of synchronous motors and induction motors, and BLDC motors.
In order to effectively control these motors, it is necessary to comprehensively acquire various related technologies, including the basic operating principles of the motors themselves, driving methods, control theory, and power conversion devices.

This book covers all of these topics together, and also explains how to simulate these techniques using Matlab/Simulink.

The structure of this book is as follows.
First, Chapter 1 describes the basic rotational principles of electric motors and the basics of electric motor operation.
Chapter 2 describes the torque control technique for controlling DC motors, which have been widely used as control motors, and explains the design of the current controller and speed controller required for this and the power conversion device that drives them.
Chapter 3 examines BLDC motors, which are not classical motors but are widely used in the field of small motor drives as a replacement for DC motors.
Chapter 4 describes the basics of AC motors, such as induction motors and synchronous motors, which are currently the mainstream industrial motors.
Chapter 5 and onwards describes advanced control of AC motors used in industrial fields.
For high-performance control of AC motors, the basic theory, concept, and implementation method of vector control technique were explained, and the current controller, PWM inverter, field weakening control for high-speed operation, and sensorless control technique required for such control were described.
Chapters 1-4 are suitable for undergraduate students who want to understand the basics of motor control, and Chapters 5 and onwards would be good for engineers who have acquired these basics or for graduate students.

This book does not simply explain the technology of using motors used in simple devices or toys, but rather aims to systematically understand, acquire, and apply the concepts of operation and control based on the formulas describing the electric motor. Therefore, if you are considering choosing this book, please keep this in mind in advance.
The author hopes that this book will help many engineers who deal with electric motors, which provide the main power for modern society, to more easily understand their control methods.
