Abstract
The present paper is a part of the study of Direct Torque Control based (DTC)
on space vector modulation using predictive controller (Predictive SVM) of a
permanent magnet synchronous motor (PMSM) powered by a photovoltaic (PV)
source. In the conventional direct torque control (DTC) of a permanent
magnet synchronous motor (PMSM), hysteresis controllers are used to choose
the proper voltage vector resulting in large torque ripples. The direct
torque control can accelerate the torque responses but increases the torque
ripple at same time. Nowadays, exist some other alternative approaches to
reduce the torque ripples based on (Predictive SVM) technique. This method
is based on the replacement of hysteresis comparators (used in conventional
DTC) by Proportional Integral (PI) regulators and the selection table by
space vector modulation (SVM). The simulation results confirm that this
proposed method where the control of the switching frequency is well
controlled, allows us to reduce the oscillations of the electromagnetic
torque and flux by 20 % and 30%, respectively with a good dynamic response
compared with conventional DTC.
