 Abstract
This paper presents identification algorithms for 1st and 2nd order processes, in dynamic regime. Each algorithms category was implemented into a software system, with an user-friendly interface. The program has different features, among them being the possibility for the user to load the file with the experimental data, dynamic model selection, module parameters calculation and graphic comparison between the experimental data and the computed mathematical model. The paper also contains case studies that outline the program’s features and the used algorithms performances.

 Rezumat
Lucrarea prezinta algoritmi de identificare in regim dinamic pentru procesele de ordinul I si ordinul II. Fiecare categorie de algoritmi a fost transpusa intr-un sistem de programe software prevazut cu o interfata utilizator prietenoasa. Programul dispune de functii care permit incarcarea fisierului cu date experimentale, selectarea modelului dinamic dorit, calculul parametrilor modelului si comparatia grafica dintre datele experimentale si modelul matematic calculat. Articolul contine si studii de caz care au evidentiat facilitatile programului si performantele algoritmilor utilizati.
