ABSTRACT
A new simulation technique using the boundary element method and the Kalman
filtering theory is presented for an inverse problem relating to the active control
of bending vibration of elastic beams subjected to time-harmonic excitation.
The
inverse problem is formulated in terms of the integral equation into an optimum
problem in which the optimal set of parameters should be found for the location
and magnitude of the control force.
The extended Kalman filtering theory is
applied to such a nonlinear optimization problem, and a solution algorithm is
then developed.
A couple of examples are computed and the results obtained are
discussed, whereby the potential usefulness of the proposed method is
demonstrated.
