With the performance of synchrotron radiation sources increasing significantly, higher requirements have been placed on the stability of double-crystal monochromators (DCMs). Using traditional passive vibration control techniques, such as optimized structures, elastic damping and vibration-absorbing materials, is unlikely to meet the future requirements of DCMs. The proposed method is the first attempt of an adaptive filtering algorithm based on variational modal decomposition in the field of DCMs development, which is an advancement for the development of high-performance DCMs at synchrotron radiation facilities.
