Über dieses Buch

After a brief introduction to the main law of physics and fundamental concepts inherent in electromechanical conversion, Vector Control of Induction Machines introduces the standard mathematical models for induction machines – whichever rotor technology is used – as well as several squirrel-cage induction machine vector-control strategies. The use of causal ordering graphs allows systematization of the design stage, as well as standardization of the structure of control devices.

Vector Control of Induction Machines suggests a unique approach aimed at reducing parameter sensitivity for vector controls based on a theoretical analysis of this sensitivity. This analysis naturally leads to the introduction of control strategies that are based on the combination of different controls with different robustness properties, through the use of fuzzy logic supervisors. Numerous applications and experiments confirm the validity of this simple solution, which is both reproducible and applicable to other complex systems.

Vector Control of Induction Machines is written for researchers and postgraduate students in electrical engineering and motor drive design.

Chapter 1. Concepts for Electromechanical Conversion

Abstract

This chapter is a reminder of the main physical laws and fundamentals of electromechanical energy conversion through magnetic devices. It seemed essential to reposition the modeling approach and the resulting control problems within the context of applied physics. The great discoveries of the past two centuries in electromagnetism allowed emphasizing most of the phenomena at the origin of many electrical machine inventions. It is also gradually explained that all these energetic phenomena are governed by the same universal principle of determinism, which refers to the principle of causality in physics. A basic example, based on a machine composed of a rotor coil and a stator coil, is studied so as to emphasize the articulation of the cause–effect relationships that govern any electromechanical conversion.
