Cristian Patrascioiu and Daniel Mihaescu


identification, numerical methods, parametric identification


The paper presents the authors researches in the dynamic identification domain. The focus of the paper is represented by the numerical algorithms used for dynamic identification for the SISO (single input - single output) system. The paper is structured on three parts. First part presents the principles of the identification techniques for the first order dynamic models without the dead time. The second part the authors developed three algorithms specifically for the first order dynamic models. The last part contains a case study which compares the results of the three algorithms for the same problem. Using this comparison, the authors have selected the best algorithm that will be selected to elaborate a numerical identification program.
