Control of a High-speed (<50,000 rpm) Interior Permanent Magnet Synchronous Motor
High-speed interior permanent magnet synchronous motors (HS-IPMSMs) play a critical role in modern industrial and automotive applications, yet their performance is often constrained by losses, parameter variations, and deadtime effects. This thesis investigates advanced field-oriented control (FOC) …
