摘要：
In this paper, a filed dynamic balancing method based on an extended state observer for magnetic bearing supporting rigid rotor is proposed. According to the equation of motion of the rotor supported by magnetic bearings, the extended state observer is designed. The dynamic disturbance of the system can be estimated by the input and output information of the target system. And the convergence conditions of the observer in discrete state are given. In order to remove the influence of multiple frequency disturbance and noise signals on the estimation results, a switched capacitor filter is designed to extract the synchronous component in the disturbance. For the errors existing in the system, the coefficient matrix iterative optimization method is used to improve the dynamic balance accuracy. In the actual use, this method can calculate the matrix of the optimization coefficient only through once trial weighting. And after balancing twice, the unbalanced mass of the rotor is significantly reduced. When the unit is in long-term operation, this method can be deployed in the microprocessor to monitor the rotor unbalance, which plays the role of early warning and guidance of the dynamic balancing. © 2020, Electrical Technology Press Co.
