The problem of identification of dynamic systems operating under feedback control is considered. The bias eliminated least squares (BELS) method has also been developed for identification under closed-loop system. In this paper, the equivalence of BELS method and weighted instrumental variables (WIV) method under an appropriate choice of weighting matrix for WIV method is verified through theoretical analysis and simulation studies.
