Performance Analysis of Indirect Vector Control of Induction Motor Drive Using Fuzzy Logic Controller.

The induction motors were characterized by complex, highly non-linear and time-varying dynamics, and hence their promptness control is a stimulating problem in the engineering applications especially in high performance drive system. The fuzzy logic controller is found to be a very useful technique to obtain a high performance speed control. The present approach avoids the use of flux and speed sensor which increase the installation cost and mechanical robustness. The indirect vector controlled induction motor drives involve decoupling of the stator current in to torque and flux producing components. The comparative performance of Fuzzy Logic control technique has been presented and analyzed in this work. This paper based on the speed control of induction motor (IM) using Fuzzy controller with the use of indirect vector control technique using MATLAB.
