Several transients were treated by simulation (start unloading, introducing a torque load, reversing and speed setpoint change). Then engine cushion at both loss and when starting without the damper. In addition, robustness tests on the parametric variation of (MSRB) were also performed. Based on the results of simulations, the control technique studied makes it possible to obtain good dynamic and static performances and has a robustness with respect to the external perturbation and the parametric variation. 2019-06-16T00:00:00Z https://dspace.univ-adrar.edu.dz/jspui/handle/123456789/5597 Direct Torque Control (DTC) SVM Predictive of a PMSM Powered by a Photovoltaic Source Tahiri, Fadila; Bekraoui, Fatiha; Boussaid, Ibrahim; Ouledali, Omar; HARROUZ, Abdelkader This article is part of the study of the Predictive Vector PWM-based Couple Direct Control (DTC-SVM-predictive) of a permanent magnet synchronous motor (PMSM) powered by a photovoltaic (PV) source. The Direct Torque Control (DTC-SVM-Predictive) where the control of the switching frequency is well controlled and therefore the ripples are weakened at the torque and flux levels. 2016-07-16T00:00:00Z
