Rezumat: In lucrare se analizeaza posibiltatile utilizarii in stuctura regulatorului standard PID a unei componente adaugatoare, proportionale derivatei a doua, care corespunde acceleratiei abaterii marimei reglate. Algoritmul standard PID si modificat PIDD2 sunt acordate la modelul obiectului cu inertie de ordinul doi si timp mort dupa metoda gradului maximal de stabilitate cu iteratii. Se efectueaza o analiza comparativa a rezultatelor obtinute la acordarea algoritmilor propusi la obiectul dat.

Cuvinte cheie: obiect de reglare cu inertie si timp mort functie de transfer, algoritm PID, PIDD2, parametrii de acord, acordarea algoritmului, metoda de acordare gradul maximal de stabilitate cu iteratii .

Abstract: In this paper was done the analyzation of possibilities the uses in the standard PID structure the additional component, the proportional second derivate, which corresponds with acceleration of the deviation of the control value. The standard algorithm PID and modified PIDD2 are tuned to the model object with inertia (second order) and time delay using the maximal stability degree method with iteration. It was done the comparative analyzation of the obtained results of tuning the proposed algorithms to the model object

Keywords: the control object with inertia second order and time delay, transfer function, algorithms PID, PIDD2, tuning values, the tuning algorithm, transition process, the performances, the maximal stability degree method with iteration
