Comparative study of vector control of induction motor by using PI controller and fuzzy controller

Induction Motors have wide variety of applications because of their advantages like rugged development, low cost and powerful performance. In latest years, more than a few facets are investigated concerning controlling induction motor. In previous year's scalar control is use for controlling purpose it is also called V/F control. It is very simple method but the main disadvantages of this method are poor dynamic performance and also it takes more time to come in stable position. After this method vector control is used. Vector control method is more complex as compare to scalar control. The VCIM drive includes decoupling of the stator current component this produces torque and flux of induction motor. It has servable advantages like good transient and dynamic performance. But it has some disadvantages like large ripple in torque in the time of starting of IM. In this paper, speed control of an induction motor (IM) using vector control with fuzzy logic and PI controller procedure has been developed and simulated. The comparative study of VCIM with PI and VCIM with fuzzy logic is done on MATLAB/SIMULINK software. Results show the effectiveness of vector control with fuzzy logic controller over traditional PI based vector control method.
