ROBUST DTC BASED ON ADAPTIVE FUZZY CONTROL OF DOUBLE STAR SYNCHRONOUS MACHINE DRIVE WITH FIXED SWITCHING FREQUENCY

Djamel Boudana – Lazhari Nezli – Abdelhalim Tlemçani – Mohand Oulhadj Mahmoudi – Mohamed Tadjine

   The double star synchronous machine (DSSM) is widely used for high power traction drives. It possesses several advantages over the conventional three phase machine. To reduce the torque ripple the DSSM are supplied with source voltage inverter (VSI). The model of the system DSSM-VSI is high order, multivariable and nonlinear. Further, big harmonic currents are generated. The aim of this paper is to develop a new direct torque adaptive fuzzy logic control in order to control DSSM and minimize the harmonics currents. Simulations results are given to show the effectiveness of our approach.

Keywords: double star synchronous machine (DSSM), direct torque control (DTC), tree level inverter, fixed switching frequency adaptive fuzzy control, harmonic currents
