This book focuses on the control strategies for gearless permanent magnet synchronous motor traction elevators. Both basic principles and experimental evaluation have been addressed. This is achieved by providing in-depth study on a number of major topics such as speed detection at low-speed operation, starting torque strategy based on dichotomy and staircase methods, fuzzy self-tuning method, MPC and ADRC, etc. The comprehensive and systematic treatment of control strategies for cost-effective gearless PMSM traction elevators and practical issues are the major features of the book, which is particularly suited for readers who are interested to learn the control strategies for cost-effective gearless PMSM traction elevators. The book benefits researchers, engineers, and graduate students in the fields of ac motor drives and control strategies for cost-effective gearless PMSM traction elevators, etc.

This book focuses on the advanced control of reduced dc-link capacitance AC motor drives. The control strategies proposed in this book are verified by experimental results, which include high power factor control, drive system stability control, beat phenomenon suppression, enhanced flux-weakening control, anti-overvoltage control, etc.
