Magnetic suspension rotor same-frequency vibration torque suppression method based on double-channel wave trap

Abstract

The invention discloses a magnetic suspension rotor same-frequency vibration torque suppression method based on a dual-channel wave trap, wherein the method comprises the following steps: firstly, building a magnetic suspension rotor dynamic model considering rotor dynamic unbalance, and then employing the magnetic suspension rotor same-frequency vibration torque suppression method based on the dual-channel wave trap. The dual-channel wave trap can accurately suppress the same-frequency vibration torque, the vibration in the X direction and the vibration in the Y direction are suppressed at the same time through one controller, and hardware computing resources are small. Meanwhile, the absolute stability of the system in a larger frequency range can be ensured by introducing a phase compensation angle. The double-channel wave trap controller disclosed by the invention is simple in structure, is convenient in practical application, and is suitable for inhibiting the same-frequency vibration torque of the magnetic suspension control torque gyroscope with dynamic unbalance of the rotor.

technical field [0001] The invention relates to the technical field of magnetic suspension control torque gyro vibration suppression, in particular to a method for suppressing the same-frequency vibration torque of a magnetic suspension rotor based on a dual-channel trap, which is used to control the simultaneous vibration of a magnetic suspension control torque gyro rotor system within the full operating speed range. The high-frequency vibration torque is suppressed to provide technical support for the application of the magnetic levitation control torque gyro on the "ultra-quiet" and "ultra-stable" satellite platforms. Background technique [0002] The control torque gyro has the characteristics of large output torque and fast response speed, and is an ideal attitude control actuator for agile maneuvering satellites. The magnetic levitation control moment gyro uses active magnetic bearings to realize the non-contact support of the rotor, which has the advantages of no fric...

Problems solved by technology

Suppressing the coil current can suppress most of the vibrations, but there are still some residual displacement stiffness forces

And many methods are aimed at the same-frequency vibration force suppression. The same-frequency vibration torque is coupled in the X direction and the Y direction due to the strong gyro effect at high rotor speeds, which brings difficulties to the design of the suppression algorithm. The research on vibration torque suppression is still To be in-depth
