acoustic box are suggested in this paper: the finite element (FE) approach and the subspace identification. Both approaches result in a state-space model, which can be used for obtaining the frequency responses and for the controller design. In order to validate the developed FE model and to perform the subspace identification, an experimental setup with the acoustic box and dSPACE system was used. Experimentally obtained frequency responses show good agreement with the frequency responses… CONTINUE READING
