| Abstract: | A new parameter identification method for a class of closed-loop linear systems with unknown feedback parts is proposed in this paper,which only the measuring data of the outer output and input of the closed-loop systems are used for identifying the forward part,feedback part and the noise model of the systems. Finally,computer simulations show the effectiveness of the identification method proposed in this paper. |
