Field-Oriented Motor Control

Abstract

Electric motors have been ubiquitous for 100 years or more and were controlled using mechanical or analog methods. Today, motors are increasingly digitally controlled, which can provide greater performance, reliability, and efficiency. This chapter will first give an overview of electric motor theory and operation and then introduce a basic digital motor control algorithm known as field-orientated control.
