In this paper, we derive a method of estimating a model set for a continuous-time delay system. Using δ-operator model, we first transform the estimation problem of a continuous-time delay system to a discrete one in which the system parameters remain in their original form. Then an identification method combining the genetic algorithm (GA) with the modified ellipsoid-bounding (MEB) algorithm is developed in order to estimate the time delay and system parameters together with their bounds. Simulation results are included to show the effectiveness of the present method. Furthermore, the present technique is applied to a closed-loop identification and a robust I-PD controller design.
