AI Technical Summary
In the current loop control of the bearing coil current of the magnetic levitation bearing, the current response speed is not timely, which causes the magnetic levitation compressor to become unstable after being subjected to impact force.
By setting up a current compensation device, the current current value of the bearing coil and the reference current value output by the displacement loop are detected. If the current reference current value is greater than the sum of the current value and the compensation current value, the current compensation device is turned on for negative compensation; if the detected current value is less than the compensated current value, the current compensation device is turned off, thereby realizing dynamic compensation of the current loop.
This improves the operational stability of the magnetic levitation bearing, prevents the magnetic levitation compressor from becoming unstable under impact, and enhances the operational stability of the magnetic levitation compressor.
