Abstract
A bias correction method without noise modelling was recently proposed for indirect identification of closed-loop systems. A key assumption used in deriving this method required that the order of the controller is not less than that of the open-loop plant. A significant feature of the results presented in this paper is the removal of this assumption to enable the method to be applicable to unbiased identification of closed-loop systems with low order controllers.
