More Information
Summary:The invention relates to the technical field of magnetic bearing systems, and discloses a method for reducing impact in a magnetic bearing system in a rotor falling process. The method comprises the following steps of: S1, calculating an output position command for reducing impact of a rotor in a falling process; 2, calculating an output current command according to the output position command; S3, converting the output current command into a current value; and S4, converting the current value into electromagnetic force for controlling a rotor position, and controlling the rotor position by using the electromagnetic force. Due to the adoption of the method, the impact in the magnetic bearing system in the rotor falling process can be reduced.
