Abstract :
In this paper, bias-compensated least squares (BCLS) method is proposed in order to estimate a plant under feedback control when the noise is colored. The feedback controller is assumed to be linear time invariant discrete-time system and the feedback system is assumed to be asymptotically stable. The aim of the proposed method is to reduce the computational cost which will be required for the conventional method.
