Abstract
In this paper we derive a generic indirect approach of closed-loop identification in order to compare estimated model of the closed-loop transfer function versus reconstructed estimated model of the open-loop plant in terms of asymptotic bias and variance considerations. We show the impact of the sensitivity function on both estimates.
