“…Magnetically suspended control sensitive gyroscope (MSCSG) is a typical magnetically suspended rotor system. Full active magnetic bearing is used to control the axial and radial suspension of the rotor, and Lorentz force magnetic bearing (LFMB) is used to control the two-degree-offreedom tilt of the rotor [6]- [8]. Taking MSCSG as an example, the structure and working principle of magnetically suspended rotor system are introduced.…”

Recently, magnetic bearings have been widely used in inertial actuators of spacecraft. Aiming at the problem of unbalanced vibration in magnetically suspended system, the research status of active vibration control method is described in detail. Firstly, the structure and working principle of magnetically suspended system are introduced, and the causes of unbalanced vibration are expounded. Then, the research status of active vibration control methods at home and abroad is introduced from two aspects of synchronous vibration and harmonic vibration, and the advantages and disadvantages of each control method are summarized. Finally, the future development trend of active vibration control technology for magnetically suspended system is prospected.

“…14 The micro-gimbal moment of magnetically suspended flywheel (MSF) has been employed to realize the active vibration control of spacecraft. 15,16 An integration control method of attitude and vibration is further proposed by magnetically suspended control moment gyros (MSCMG). 17 However, the attitude control and vibration suppression can only be carried out at different times, 17 that is, they cannot be performed simultaneously, which inevitably influences the dynamic performance of spacecraft.…”

“…18 However, the complicated situations such as difficult measurement of micro-vibration, unknown moment of inertial of spacecraft and parameter changes have not been considered in the earlier study. [14][15][16][17][18][19] This paper proposes a synchronous control method of spacecraft attitude and micro-vibration based on MSCSG. The attitude control and vibration suppression of spacecraft are realized simultaneously by the gimbal rotation and rotor deflection of MSCSG.…”

This paper puts forward realizing the synchronous control of spacecraft attitude and micro-vibration by taking advantage of magnetic suspension rotor deflection of magnetically suspended control and sensitive gyro. A disturbance-observer is designed to estimate the complex micro vibration which is hard to measure, and an adaptive robust sliding mode controller is designed as an integrated controller and its stability is proven by Lyapunov stability criterion. The band-pass filters are introduced to separate low frequency and high frequency control signals and takes them as input commands of gyro frame and magnetic suspension rotor, respectively. The semi-physical simulation results testify that the proposed method has good vibration suppression effect as well as improves the attitude convergence rate.

“…It provides the accurate attitude control torque for spacecraft by regulating the rotor speed [1]- [3]. Suspended by the active magnetic bearings (AMBs), the magnetic suspended flywheel (MSF) has the advantage of high accuracy, long life, compact size, and low power consumption [4]- [5]. Besides, owning to the closed-loop control, the base can avoid the influence from the rotor unbalanced vibration.…”

In order to attenuate the vibration caused by the radial imbalance in the Magnetically Suspended Flywheel (MSF), a parallel automatic balance control method is proposed. First, after the conduction of comparison between the parallel and series notch filter, a conclusion is drawn that the MSF achieves a better dynamic performance with greater attenuation on current vibration using the parallel notch filter. Then, experiments are performed under three conditions: without using the unbalance control, using radial unbalance control, and using axial unbalance control. The experimental results indicates that the stable automatic balance control and faster converging speed are achieved with the adoption of the proposed method. Furthermore, the vibration on the base is reduced significantly when the proposed method is introduced for all channels.
