Performance Analysis of Fuzzy Based Sliding Mode and Self-Tuning Controls of Vector Controlled Induction Motor Drive
Keywords:Induction motor, Field Oriented Control, Fuzzy logic Controller, self tuning control and Sliding Mode Control.
This paper presents the fuzzy based sliding mode and self tuning controls for Indirect vector controlled induction motor drive. Because of the low maintenance and robustness induction motors have many applications in the industries. The speed control of induction motor is more important to achieve maximum torque and efficiency. Soft computing technique Fuzzy logic is applied in this paper for the speed control of induction motor to achieve maximum torque with minimum loss. The fuzzy logic controller is implemented using the Field Oriented Control technique as it provides better control of motor torque with high dynamic performance. The proposed adaptive controller takes advantage of sliding mode control and fuzzy logic control. The chattering effect is attenuated and robust performance can be ensured .The simulated design is tested using various tool boxes in MATLAB. Simulation results conclude that the proposed fuzzy based controller showed increased dynamic response.
