| titleOfInvention | Method for observing unbalanced excitation of rotor and inhibiting displacement vibration of magnetic suspension bearing system |
| abstract | The invention discloses a method for observing unbalance excitation of a rotor of a magnetic suspension bearing system and inhibiting displacement vibration, and belongs to the field of magnetic suspension bearing control. The method comprises the steps of converting a rotor coordinate into a translation-rotation coordinate, resolving excitation caused by a supporting force of a magnetic suspension bearing and a rotor gyro effect, and observing unbalanced excitation by a generalized integral extended state observer. After the unbalanced excitation is effectively observed, a command in a direction opposite to the unbalanced excitation obtained by observation is injected into the command of the power amplifier to generate electromagnetic force for counteracting the unbalanced excitation, so that the effect of restraining the displacement vibration of the rotor is achieved. The rotor displacement vibration is restrained, the rotation precision of the rotor can be improved, and the collision and abrasion risk is reduced. The method is also of great significance for the compensation mass calculation during the dynamic balance of the rotor by observing the unbalanced excitation. |
