Real number laplace transformation-based identification for first-order system including time-delay

This paper proposes a simple yet effective identification method for a first-order system including a time-delay. This method is based on the Laplace transformation in real number domain and is able to estimate both coefficients of the first-order system and the time-delay simultaneously. The accuracy of the identification results was analyzed using simulation. Precise estimation of the present method was confirmed compared to an orthodox on-line estimation technique utilizing a bilinear-model. Furthermore, a guideline for tuning the parameters used in the method is shown.
