Abstract

In this paper, a dual stator induction machine is studied. This nonlinear system is built on the Matlab/Simulink tool to test the efficiency of the direct torque control loop for controlling this complicated system. It makes the speed and torque tracking more comfortable. On the other side, it is mandatory to assure the independence of the electrical alimentation of the dual stator. All these goals are guaranteed with this direct torque control technique. The conventional direct torque control loop is based on the switches’ controllers. This method makes many fluctuations in the speed performances, the flux evolution, and the electromagnet torque progress. The conventional direct torque control drawbacks are resolved by improving this control loop using the fuzzy control topology. Then, an improved direct torque control loop using the intelligent controllers is presented to control the torque and speed of a dual stator induction machine and supervise the two stator fluxes and currents. Matlab/Simulink tool was used for implanting this innovation and showing the behavior of the results.

Summary

INTRODUCTION

Electrical motors were used mainly in blowers, pumps, fans, and machine tools applications. If concentrating on electric vehicle applications and efficiency, which needs a high-power machine with a small size, and if focused on low wind speed in some situations, the dual stator machine was resolved some of these problems. The main point inside this research work is to give the corresponding direct torque control architecture adapted for this complicated machine design and resolve the ripples and fluctuations problems using the fuzzy logic solution. The proposed control pack assures the independence between the two stators alimentation and in what way is this is validated, presents another key of this paper This issue will resolve the problems confronted by authors in these references [25,26] and related to the system's instability in other control solutions. A conclusion part resumes the paper objectively and cites selected perspectives for this work
