High-Performance Control for Permanent Magnet Synchronous Motors

This publication was made possible through the support of Nantong Institute of Technology. The electric machine as the core device for electromechanical energy conversion is the cornerstone of modern industrial civilization. From the invention of the electric motor in the nineteenth century to the present day every technological leap in electric machinery has profoundly transformed human production and daily life. In the twenty-first century as the energy crisis intensifies and environmental concerns become more prominent developing efficient and clean electric-drive technology has become a global consensus. Against this backdrop the permanent-magnet synchronous motor (PMSM) is emerging as the mainstream choice for next-generation electric-drive systems thanks to its outstanding merits of high efficiency high power density and high reliability.
