为了提高航天器的敏捷性和超静定性能，提出了采用单框架磁悬浮控制力矩陀螺金字塔构型实现航天器姿态机动和微振动抑制双重控制的设想，利用陀螺框架的旋转实现快速姿态机动，利用磁悬浮转子的偏转实现高精度微姿态机动。航天器姿态/振动控制器的切换设计，实现了陀螺框架和磁悬浮电机的协调工作，体现了双执行机构的控制优势。该策略不仅加快了航天器姿态机动过程，改善了动态响应，而且缩短了姿态稳定调整时间，提高了稳定精度，保证了姿态机动后振动的快速抑制。此外，该方法具有较强的鲁棒性，在参数变化的情况下，保证了航天器姿态控制与振动抑制一体化的顺利实施。仿真结果表明了该策略的有效性和优越性。
For the sake of improving the agility and super-static performance of spacecraft, this paper puts forward an idea for using single gimbal magnetically suspended control moment gyroscope pyramid configuration to realize dual control of attitude maneuver and micro-vibration suppression of spacecraft, in which gyro gimbal rotation is used to realize fast attitude maneuver and magnetic suspension rotor deflection is used to realize high-precision micro-vibration suppression of spacecraft; the switching design of spacecraft attitude/vibration controller realizes the coordinated operation of gyro gimbal and magnetic suspension motor, showing the control advantage of dual actuators. This strategy not only speeds up the attitude maneuver process of spacecraft, improving the dynamic response, but also reduces the attitude stabilization adjustment time as well as improves the stabilization precision, ensuring the fast vibration suppression after attitude maneuver. In addition, this method has strong robustness ensuring the smooth implementation of spacecraft attitude control and vibration suppression integration in the case of parameter change. The simulation results show the effectiveness and superiority of this strategy.
