CRC Press Permanent Magnet Synchronous Machines and Drives - Flux Weakening

This comprehensive technical reference explores permanent magnet synchronous motors (PMSMs) and their critical role in electric vehicle propulsion systems, where high-power density and reliability are essential. The book presents an improved field-oriented control (FOC) strategy for PMSMs utilising optimal proportional-integral (PI) parameters to achieve robust stability, faster dynamic response, and higher efficiency in the flux-weakening region. Coverage includes the combined design of a PI current regulator with varying switching frequency pulse-width modulation (PWM), alongside improved linear model predictive control techniques. Ideal for engineers, researchers, and students working with electric motor control systems, power electronics, and advanced drivetrain technologies.
