| Details | In this research, the identification results for open-loop time delay systems are extended to closed-loop systems. It is shown that a subspace identification method used in open-loop systems can be applied to closed-loop systems. When the subspace identification method was used directly, problems such as increasing poles and unstable zeros caused by numerical errors were encountered; however, these problems can be prevented by a shift operation. Finally, the simulated identification results for the time delay system and the improved control performance using the estimated time delay are shown. |
