Abstract： The vehicle industry is an important pilar of the national economy，thus the development of hydrogen fuel cell technology is of great significance for promoting clean energy transformation，sustainable development and scientific and technological innovation. As the power source of the air compressor， the ultra-high-speed permanent magnet synchronous motor （UHS-PMSM） sufers from inherent limitations in their sensorless control algorithms，including limited control accuracy，poor robustness，and sensitivity to changes in the working environment. Therefore，this study conducted an in-depth investigation into the control strategy of the UHS-PMSM based on the project requirements.By refining the relevant sensorless control algorithms， stable motor control under ultra-high-speed conditions was achieved. In addition，the test rig including motor and controller，air compressor and test instruments had ben established to verify the reliability of the sensorless control algorithm.The results indicated that the accuracy and stability of UHS-PMSM sensorless control algorithm had been improved significantly. Specifically，the estimation error of the control system at 2.0×104r/min was reduced by 25% ，the total harmonic distortion（THD） value decreased from 4. 81% to 2. 80% as well. Simultaneously，the phase delay problem of the position estimation was optimized obviously.
