VOLTAGE CONTROLLED OPTIMAL ELECTRICAL DRIVE SYSTEM WITH VARIABLE TORQUE

Autor/autori: Prof. Corneliu BOTAN, PhD, Lecturer Florin OSTAFI, PhD

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.

Cuvinte cheie: actionare electrica, cuplu rezistent variabil, control optimal liniar patratic 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.

Keywords: electrical drives, variable load torque, discrete linear quadratic optimal control
