High-Performance Control of Synchronous Machines

7.1 Introduction

Synchronous machines are widely used as both generators and motors. Power generation plants use synchronous generators to convert large amounts of mechanical energy to electrical energy, which is then transmitted to commercial, industrial, and residential consumers. Synchronous motors are available in a variety of forms and ratings from fractional Watts to hundreds of kilowatts.

The focus of this chapter, in the context of electric drives, will naturally be on synchronous motors and methods for controlling their torque and speed. In particular, we will study synchronous machines with PMs on their rotor to establish a magnetic field. Such machines are available in two ...
