Features: This book introduces the specific circuits, working principles, parameter design, and adjustment methods of sensorless vector control systems. Additionally, it presents several typical sensorless speed estimation and observation schemes. At the end of the book, technical data and specifications of the latest sensorless vector control frequency converters from Japan, France, the UK, the US, Germany, and other countries are listed for reference. This revision primarily adds Chapters 8 and 9, covering the theory and practice of speed estimation and flux observation in sensorless vector control systems. Over the past eight years, research in this field both domestically and internationally has attracted attention from academia and industry, making it a hot topic. This revision provides different speed estimation schemes from well-known foreign frequency converter manufacturers. Furthermore, the latest theory of speed estimation, the Model Reference Adaptive System (MRAS), has transitioned from pure theoretical and computer simulation research several years ago to a practical stage. The book also cites numerous application examples and new solutions for sensorless control systems based on MRAS, both domestically and internationally, along with industrial application achievements. This book is primarily intended for engineering technicians engaged in electrical drive automation technology, but it can also serve as a reference for faculty and students in relevant fields at universities and colleges.
