Abstract EN
The magnetically suspended control moment gyros (MSCMGs) are complex system with multivariable, nonlinear, and strongly gyroscopic coupling.
Therefore, its reliability is a key factor to determine whether it can be widely used in spacecraft.
Fault-tolerant magnetic bearing systems have been proposed so that the system can operate normally in spite of some faults in the system.
However, the conventional magnetic bearing and fault-tolerant control strategies are not suitable for the MSCMGs because of the moving-gimbal effects and requirement of the maximum load capacity after failure.
A novel fault-tolerant magnetic bearing system which has low power loss and good robust performances to reject the moving-gimbal effects is presented in this paper.
Moreover, its maximum load capacity is unchanged before and after failure.
In addition, the compensation filters are designed to improve the bandwidth of the amplifiers so that the nutation stability of the high-speed rotor cannot be affected by the increasing of the coil currents.
The experimental results show the effectiveness and superiority of the proposed fault-tolerant system.
