The invention relates to a rapid vibration suppression method for a lorentz force magnetic levitation satellite load cabin. A satellite load cabin dynamic model is established based on a satellite load cabin five-degree-of-freedom control scheme, and the final deflection angular velocity of a load cabin is obtained by performing information fusion on deflection control current and the deflection angular velocity of the load cabin obtained by two schemes of an inertial measurement unit and an angular displacement sensor. And Fourier transform is carried out to obtain the vibration frequency of the load cabin. And the frequency is updated to an adaptive frequency tracking wave trap in real time, so that extraction and feed-forward compensation of vibration components are realized, and the purpose of vibration suppression of a satellite load cabin is achieved. The vibration suppression process is completely realized through an algorithm, and the calculation amount is relatively low, so that the method has rapidness. The load cabin vibrates after rapid maneuvering, and by means of the method, the stabilization time of the load cabin of the Lorentz force magnetic levitation satellite after rapid maneuvering is effectively shortened. The method belongs to the field of spacecraft attitude control, and can be applied to high-precision stable control of spacecraft attitude vibration.
本发明涉及一种洛伦兹力磁浮卫星载荷舱快速振动抑制方法。基于卫星载荷舱五自由度控制方案建立卫星载荷舱动力学模型，通过将偏转控制电流与惯性测量单元和角位移传感器两种方案得到的载荷舱偏转角速度进行信息融合得到载荷舱最终的偏转角速度，并进行傅里叶变换得到载荷舱的振动频率。将该频率实时更新至自适应频率跟踪陷波器中，实现振动成分的提取与前馈补偿，达到卫星载荷舱振动抑制的目的。由于振动抑制过程完全通过算法实现，且计算量较低，故该方法具有快速性。载荷舱在快速机动后存在振动，通过该方法有效降低了洛伦兹力磁浮卫星载荷舱快速机动后的稳定时间。本发明属于航天器姿态控制领域，可应用于航天器姿态振动的高精度稳定控制。
