Combining the wavelets and least mean square (LMS) algorithm, this paper focuses on adaptive vibration control to sheet metal by using decomposition LMS algorithm. In order to realize the realtime of wavelets adaptive algorithm, t h e fast MALLAT algorithm was adopted. The simulation and experimental results sho w that the method, compared with the traditional LMS algorithm, effectively redu ces the autocorrelation of the input signal correlation matrix, and the converge nce speed and steadystate performance are significantly improved.
