磁悬浮离心式压缩机在线参数辨识的无位置传感器驱动

With the advantages of a high power-to-weight ratio and oil-free bearings, a magnetically suspension centrifugal compressor (MSCC) equipped with active magnetic bearings operates more efficiently than the traditional mechanical compressors over a wide speed range by precisely controlling a high-speed permanent-magnet synchronous motor (PMSM). However, owing to the harsh working environment, the mo...
