Book Review: Measurement and Instrumentation for Control

Chapters 3 and 4 are concerned with the interaction of the d.c. motor with converters based on single-phase and three-phase rectifiers of various configurations. Chopper-controlled motors are analysed in Chapter 5. Chapters 6 to 10 are devoted to drives based on induction motors. These include drives based on reduced voltage, slip-energy recovery, constant-current inverters and constant-voltage inverters. Finally, the synchronous motor and its drive circuits are analysed in Chapter 11. There are several useful worked examples included throughout the text, and a collection of problems at the end of each chapter (answers provided). The authors are prepared to supply solutions to these problems on request. Inevitably, in a book of this type, some aspects of drives are omitted and some subjects receive a rather cursory treatment e.g. only 3 paragraphs are allocated to the cycloconverter. Also, there is no attempt to deal with the transient behaviour of drive systems. Perhaps this is no bad thing, since the inclusion of extra material would increase the already astronomical price of this book (£57.75). G. H.
