In the speed control of induction motors, an acceptable good performance cannot be obtained by using traditional feedback controllers due to the non-linear structure of the system, the effects of changing environmental conditions and several disturbance inputs. On the other hand, in recent years, it has been demonstrated that artificial intelligence based control methods were much more successful in the nonlinear system control applications. In this study, an intelligent controller has been developed for speed control of induction motors by using radial basis function neural network (RBFNN) and model reference adaptive control (MRAC) strategy. In the driving of induction motor, indirect field oriented vector control method which is widely used in high-performance drive system has been preferred. Simulation results to determine the success of the development of this control method was compared with conventional PI type controller. While the motor is under the fan-type load, the performance of controller has been investigated in Matlab/Simulink environment. The simulation results demonstrate that the performance of RBFNN based MRAC controller is better than that of conventional PI controller.
