Electrical drive control is well known for regulating the magnetic flux and torque.

These controls also use some electrical and mechanical variables that are not directly measurable. The authors, with great experience in the domains of research, teaching and industrial applications, develop methods and realizations in identification, estimation and observation.

The measurement and identification of the parameters of electrical machines and some state observers for them are studied in this book. Also, several experiments are performed concerning some deterministic and stochastic state observers for these machines.

This book will hold great interest for scientific and industrial researchers in the field of variable speed drives.
