In the speed control of three-phase induction motor, conventional PI type control can not provide a good performance due to non-linear structure of the system, change in load torque, change in parameters and unknown disturbance effects. Therefore, adaptive control methods have been applied in speed control of induction motor in order to obtain better performance. In this study of speed control of vector controlled induction motor, adaptive neuro-fuzzy inference system (ANFIS) which is one of modern control techniques are commonly proposed compared to conventional PI control. The aim of the study is to set the parameters of proposed controller and to obtain high performance in speed control of induction motor by using obtained input-output data over PI control. The performance of both the control systems in MATLAB/Simulink environment was investigated in case of different operating conditions. In this simulation study of speed control of induction motor, the suggested controller produces better performance compared with the conventional PI controller by arranging the performance parameters such as rise time, overshoot, settling time and steady state error. Besides, it is observed that in the region of change in reference speed and change in load, ANFIS provided better performance than PI type control.
