Identifiability conditions for linear systems operating in closed loop

Forskningsoutput: TidskriftsbidragArtikel i vetenskaplig tidskrift

Abstract

The problem of identifiability of processes using measurements obtained under closed loop operation is treated. Single input-single output systems are considered. It is assumed that the feedback is time invariant, linear and noise free. It is also assumed that no external input signal is injected. Conditions, which are simultaneously necessary and sufficient for identifiability are derived. The results are illustrated by a few numerical examples.
