Closed-loop Identification of Finite Impulse Response for Systems Subject to Complicated Disturbance

In this paper, we propose a novel method for identifying the Finite Impulse Response (FIR) of the closed-loop systems subject to complicated disturbance. The presented algorithm is a two-step robust identification method, which offers a solution to the challenge of dealing with complicated disturbance. The first step is to correct the process output in the frequency domain, and the second step is to identify the FIR parameters of model through the processed data. The illustrative simulation example serves to demonstrate the effectiveness of the presented approach.
