An extended and improved discrete space vector modulation direct torque control for induction motors
2004 IEEE 35th Annual Power Electronics Specialists Conference (IEEE Cat. No.04CH37551), 2004In the classical DTC scheme, due to the limited number of the VSI voltage vectors, large and small errors can not be distinguished. In fact, the switching vectors chosen for large errors are the same as those chosen for small errors. In this paper, in order to overcome this problem, after considering the primary ideas of the DSVM-DTC technique, a new ...

A control strategy of direct torque control (DTC) based on discrete space vector modulation (DSVM) system of induction motor fed with GTO voltage source inverter applied to railway traction is introduced. The switching frequency cannot be high in high power GTO inverter applications. When direct torque control of induction machines is implemented using

A method is proposed for torque control of permanent magnet synchronous motors with lower switching frequency than SVM-based methods. This method takes the advantages of discrete SVM while a complicated switching table is avoided. Owing to the Deadbeat stator current control, the proposed control does not require stator flux estimation. Compared to the

In this paper, an uniform mathematic model of three-level inverters feed induction motor drives system has been constructed. Based on the application of the discrete space vector modulation (DSVM), a DTC strategy of three-level inverters induction motor drives system is proposed. With DSVM-DTC algorithm, the neutral-point (NP) voltage balancing problem

In this paper, discrete space vector modulation (DSVM) technique for induction machine drives is developed, and then a fuzzy logic direct torque control (DTC) scheme based on the proposed DSVM technique is presented. In DSVM technique, new voltage vectors are synthesized by applying three standard voltage space vectors for three equal time intervals at

This paper presents a new direct power control (DPC) strategy for a double fed induction generator (DFIG) based wind energy generation system. The strategy of the discrete space vector modulation (DSVM) that is on the basis of the DPC, is implemented. The algorithm to select voltage vector can effectively change the response of the system.
