Rezumat
Se prezinta o problema de control optimal din punct de vedere energetic al unui sistem de actionare electrica. Se are in vedere o variatie treapta a cuplului rezistent in intervalul de optimizare. Criteriul de performanta tine cont doar pierderile Joule, deoarece acestea depasesc in mod semnificativ alte pierderi in perioada tranzitorie. Lucrarea se refera la o structura cu control in tensiune a sistemului de actionare. Studiul se prezinta in domeniu de timp discret.

Abstract
The optimal control from the energetic point of view of the transient state of electrical drive systems
is presented. A step variation of the load torque in the optimization interval is considered. The performance
criteria consider only Joule losses, since they significantly overcome other ones in the transient state. The paper
refers to a structure with voltage control of the drive. The study is performed in discrete time domain.
