Sensorless speed control of induction motors has become a mature
technology in the past decade. Eliminating the speed sensor on the
motor shaft represents a cost advantage, which combines favorably with
increased reliability that results from the absence of a mechanical
transducer and its sensor cable.

On-going research is focused on providing sustained operation at high
dynamic performance in the very low speed range including zero speed
and zero stator frequency. Such specifications are satisfied by
accurate modelling of the machine and the nonlinear inverter, and by
fast on-line parameter adaptation.

An overview is given on sensorless speed control which uses signal
flow graphs of complex space vector quantities to give an insightful
description of the physical and mathematical systems used in
sensorless control. The performance at different operating conditions
is illustrated by short movies.


Joachim Holtz graduated in 1967 and received the Ph.D. degree in 1969
from the Technical University Braunschweig, Germany.

In 1969 he became Associate Professor and, in 1971, Full Professor and
Head of the Control Engineering Laboratory, Indian Institute of
Technology in Madras, India. He joined the Siemens Research
Laboratories in Erlangen, Germany, in 1972. From 1976 to 1998, he was
Professor and Head of the Electrical Machines and Drives Laboratory,
Wuppertal University, Germany. He is presently Professor Emeritus and
a Consultant.

Dr. Holtz has extensively published, among others 12 invited papers in
journals. He has earned 15 Prize Paper Awards. He is the co-author of
four books, and holds 32 patents.

Dr. Holtz is the recipient of the IEEE Industrial Electronics Society
Dr. Eugene Mittelmann Achievement Award, the IEEE Industrial
Applications Society Outstanding Achievement Award, the IEEE Power
Electronics Society William E. Newell Field Award, the IEEE Third
Millennium Medal, the Anthony J. Hornfeck Service Award, and the IEEE
Lamme Gold Medal. He is a Life Fellow of the IEEE.

Dr. Holtz is Past Editor-in-Chief of the IEEE Transactions on
Industrial Electronics, Distinguished Lecturer of the IEEE Industrial
Applications Society and IEEE Industrial Electronics Society.
