| Abstract: | This paper proposes a new robust closed loop identification algorithm to continuous systems with dead time.The transfer function of the system can be identified in the closed loop condition,with the algorithm proposed in this paper.And the resulting parameter estimation is very robust to disturbance and measurement noise in the output.Simulation results illustrate the accuracy of the proposed algorithm. |

| Keywords: | closed-loop identification continuous systems with dead time step response Laguerre models transfer function |
