Exemplu utilizare GridIdent

Aplicaţia Grid de determinare a modelelor matematice include algoritmi operând pe datele de intrare-ieşire existente sau generate, prin experimente dedicate, ale variabilelor sistemelor sau proceselor dinamice. Se pot folosi, aşadar, înregistrările disponibile în mod curent pentru urmărirea evoluţiei proceselor. Această abordare, de determinare a modelelor matematice din datele de intrare-ieşire, se numeşte identificarea sistemelor. Aplicaţia generează modele de sisteme multivariabile discrete, liniare invariante în timp (LIT), descrise în spaţiul stărilor. Ordinul sistemului poate fi impus de utilizator, sau poate fi determinat automat de aplicaţie.

Datele de intrare definesc opţiunile de rezolvare (metoda de utilizat şi parametrii asociaţi, ordinul dorit, configuraţia de procesoare, dimensiunea blocurilor, toleranţe), opţiunile de listare/memorare a rezultatelor, dimensiunile problemei şi numele fişierului conţinând matricele de date (de pildă, traiectoriile variabilelor de intrare U şi de ieşire Y ale sistemului). Matricele sunt stocate în ordinea coloanelor, iar fiecare linie din fişier conţine un singur element al unei matrice.

Datele de ieşire sunt matricele calculate; ele pot fi listate şi/sau memorate într-un fişier specificat.

Pentru identificare, vor fi executate programele : pdorder, pdsident, pdfindx0.
