Inverter-fed Induction Motor Drives

1. Introduction

We have seen in Chapter 6 why the relatively simple and low-cost induction motor is the preferred choice for many fixed speed applications, and in Chapter 7 we saw that by using field orientation/vector or direct torque control, it is possible to achieve not only steady-state speed control but also dynamic performance superior to that of a thyristor d.c. drive. We have also seen that achieving such performance is dependent on the ability to perform very fast/real-time modeling of the motor and very rapid control of the motor voltage magnitude and phase.

In this chapter we look at some of the practical aspects of inverter-fed induction motor drives and consider the impressive performance ...
