Control-relevant input excitation for system identification of ill-conditioned n×n systems with n>2

    Forskningsoutput: Kapitel i bok/konferenshandlingKonferensbidragVetenskapligPeer review


    The objective of this work is to generalize input excitation designs suggested for system identification of ill-conditioned 2x2 systems to cases with more than two inputs and outputs. The methods are evaluated using a four inputs-four outputs distillation column/stripper system as a case study. The performance of the various procedures is evaluated through the model fit and different plant-friendly indices. The obtained models, and thus the quality of the associated input excitations, are also evaluated through cross validations.
