derived signal v k the coefficients a u2032 j and b u2032 i are parameters to express the identified fluctuation u03b4j therefore control coefficients a i and b j to compensate the fluctuation u03b4j can be obtained by equation 9 as follows the control coefficients thus obtained are supplied to the adaptive filter 8 and the dynamic characteristics of the adaptive filter are modified to compensate the fluctuation u03b4j as is clear from the aforementioned detailed explanation on the adaptive controller 20 using equations when the larger one of the number of the reference signal r m and the number of the output signal v n is assumed to be an integer p max m n the white noise generator 12 need to repeatedly output only p data of white noise signal in synchronization with sampling the adaptive control device shown in fig1 may be realized as a single calculation device or a plurality of different calculation units for the respective components or groups of components fig6 shows a processing flow example when the shaking table adaptive control device of fig1 is realized by a single calculation device firstly a white noise w is generated step 601 this white noise w is used to calculate a mask signal m by equation 5 for the bandstop filter 13 step 602 next a command signal u and a shaking table response signal y are read in steps 603 and 604 according to the command signal u a modified command signal u u2032 is calculated by equation 1 for the adaptive filter 8 step 605 this modified command signal u u2032 is used to calculate a desired shaking table response signal y.
