A PM Brushless DC motor drive system is used to control the speed or the position of a Permanent Magnet Brushless DC motor. The position and speed sensors have some disadvantages such as increasing cost and reducing the drive robustness. By the reason, sensorless control has been studied for the last decades but the study has been still reminding problems. Therefore, a novel estimation technique for speed and position of PMBLDC motor is proposed. In the technique, the speed and position is calculated from estimated back-EMF which is estimated by only measurable voltages and currents of the...

The book presents high quality research papers presented by experts in the International Conference on Internet Computing and Information Communications 2012, organized by ICICIC Global organizing committee (on behalf of The CARD Atlanta, Georgia, CREATE Conferences Inc). The objective of this book is to present the latest work done in the field of Internet computing by researchers and industrial professionals across the globe. A step to reduce the research divide between developed and under developed countries.
