Due to the limitation of the machining accuracy, there exist mass imbalance and sensor runout in magnetically suspended rotor system, which will result in harmonic current in the rotor system. Harmonic current can not only increase the power consumption but also induce harmonic vibration which will be transmitted to spacecraft by magnetic bearings and affect the attitude stability of spacecraft. In order to analyze and reduce harmonic current, the model of magnetically suspended rotor system is built and analyzed. Variable-step-size FBLMS algorithm is proposed in this paper to suppress harmonic current simultaneously. According to the proposed algorithm, step size variation depending on harmonic current and individual step size is figured out for each weight vector so that each frequency component in the block can be adjusted. As a result, convergence performances are further improved by adjusting the weight vectors adaptively. The validity of the proposed method is testified by simulation. Simulation results show that variable-step-size FBLMS algorithm can reduce the harmonic current further and increase the convergence rate.

Undesired vibration force caused by harmonic currents is a common problem in a magnetically suspended flywheel (MSFW) rotor system. It poses a potential threat to system stability and performance degradation. In this work, multiple different phase‐shift notch filters are connected in parallel mode to suppress the vibration harmonics. First, the multi‐frequency vibrations in the MSFW is modelled and analysed. Then multiple different notch filters in parallel mode are proposed to plug into the baseline magnetically suspension system. The performance comparison with the conventional multiple notch filters is investigated. The parameters design and calculation for the proposed method are analysed in details. Moreover, the closed‐loop stability of the overall system is given in the full speed range. Finally, simulation and experimental results for the MSFW demonstrate the superiority of the proposed method on both harmonics suppression and stability preservation.

The advantage of magnetic forces is that they can be acted on the rotating parts contactless, thus changing the structure of the rotor little.…”

To suppress the vibration of a rotor system, a vibration absorber combining negative stiffness with positive stiffness together is proposed in this paper. Firstly, the negative stiffness producing mechanism using ring type permanent magnets is presented and the characteristics of the negative stiffness are analyzed. Then, the structure of the absorber is proposed; the principles and nonlinear dynamic characteristics of the absorber-rotor system are studied numerically. Finally, experiments are carried out to verify the numerical conclusions. The results show that the proposed vibration absorber is effective to suppress the vibration of the rotor system, the nonlinearity of the negatives stiffness affects the vibration suppression effect little, and the negative stiffness can broaden the effective vibration control frequency range of the absorber.
