Abstract

The invention discloses a magnetic suspension rotor odd harmonic vibration inhibition method based on a hybrid odd repetition controller. The magnetic suspension rotor odd harmonic vibration inhibition method comprises the following steps: firstly, establishing a magnetic suspension rotor kinetic model containing rotor mass unbalance and sensor harmonic; secondly, adopting the magnetic suspensionrotor odd harmonic vibration inhibition method based on the hybrid odd repetition controller (hereinafter referred to as HORC). The HORC is composed of an odd harmonic frequency inhibited second-orderinner film structure and a modified resonant controller (hereinafter referred to as MRSC), which are connected in parallel. The HORC can be used for improving a harmonic inhibition capability of a magnetic suspension rotor system when the harmonic frequency is perturbed, and the control robustness of a system under the harmonic frequency perturbation of the system is improved. According to the magnetic suspension rotor odd harmonic vibration inhibition method based on the hybrid odd repetition controller, an odd harmonic current component generated by a magnetic bearing coil in a magnetic suspension rotor is inhibited, so that odd harmonic vibration of the magnetic suspension rotor system with the rotor mass unbalance and the sensor harmonic is inhibited.

Description

technical field

[0001] The present invention relates to the technical field of harmonic vibration suppression of magnetic levitation rotors, in particular to a method for suppressing odd harmonic vibrations of a magnetic levitation rotor system based on a hybrid odd repetitive controller HORC (Hybrid Odd Repetitive Controller, HORC), which is applied to a magnetic levitation rotor system Vibration suppression provides technical support for the application of maglev control moment gyro on the "ultra-quiet" satellite platform. Background technique

[0002] In the Control Moment Gyroscope (CMG), the electromagnetic force of the magnetic bearing realizes the stable suspension of the rotor. Because there is no mechanical friction between the rotor and the stator, magnetic bearings have many advantages compared with mechanical bearings: first, there is no mechanical friction between the magnetic levitation rotor and the stator, and the speed of the CMG flywheel can be greatly incr...
