Hydrogen energy is a highly promising clean energy source. In a hydrogen fuel cell system, the air compressor is an ultra-high-speed permanent magnet synchronous motor (PMSM). The control objective is to compress ambient oxygen to provide a stable and precise supply for the fuel cell stack reaction. The performance of the ultra-high-speed air compressor controller is a critical determinant of stack voltage stability and catalyst lifespan; therefore, its application in fuel cell motor drive systems represents a significant research direction. This article introduces an ultra-high-speed PMSM drive system, detailing its hardware architecture and key components, followed by the implementation of sensorless Field-Oriented Control (FOC). Finally, the acceleration performance of the air compressor is experimentally confirmed, validating the feasibility of the proposed system for hydrogen fuel cell applications.
