Abstract

The invention discloses a magnetic suspension rotor harmonic vibration force inhibition method based on a multi-synchronous coordinate transformation method. The method comprises the steps of firstlybuilding a magnetic suspension rotor dynamic model comprising mass imbalance and sensor harmonic waves, and then employing the MSRFT-based magnetic suspension rotor harmonic vibration force inhibitionmethod. The MSRFT can accurately suppress harmonic vibration force, and one controller is used for suppressing vibration in the X direction and the Y direction at the same time, so that hardware computing resources are reduced, and the dynamic process of suppression is accelerated. Meanwhile, the introduction of the phase compensation angle can guarantee the absolute stability of the system in alarger frequency range. The MSRFT controller is simple in structure, convenient to use in practical application, capable of restraining harmonic vibration force in the magnetic suspension rotor, and suitable for restraining harmonic vibration force of a magnetic suspension rotor system with mass imbalance and sensor harmonic waves.

Description

technical field [0001] The invention relates to the technical field of harmonic vibration force suppression of magnetic suspension rotors, in particular to a method for suppression of harmonic vibration force of magnetic suspension rotors based on a multi-synchronous rotation coordinate transformation method, which is used to control the torque gyro rotor system of magnetic suspension within the full operating speed range The harmonic vibration force can be suppressed, providing technical support for the application of magnetic levitation control moment gyroscope on "ultra-quiet" and "ultra-stable" satellite platforms. Background technique [0002] The control moment gyroscope has the advantages of large output torque and fast response speed, and has become a key attitude control inertial actuator for high-performance satellites. Compared with traditional mechanical bearings, active magnetic bearings can realize the non-contact support of the rotor, so it has the advantages ...
