Sensorless Control for High-Speed Permanent Magnet Synchronous Motors
暫譯: 無感控制高速度永磁同步馬達

Benefiting from advancements in power electronics and automatic control technologies, the Permanent Magnet Synchronous Motor (PMSM) has emerged as a pivotal drive component in industrial automation, renewable energy, and aerospace applications, owing to its high power density, rapid dynamic response, and sensorless operation potential. However, challenges persist in achieving reliable full-speed-range (zero-low to high-speed) sensorless control due to limitations of single-method adaptability and mechanical sensor-induced cost and reliability issues. This study proposes a hybrid sensorless control framework integrating domain-specific optimization and dynamic switching mechanisms to enable seamless full-speed-range operation.
