Harmonics in Torque Characteristics when speed control by Neural network controller

I have developed dynamic model of induction motor drive with d-q model and analysis the performance of Induction motor drive using Conventional,Fuzzy,adaptive fuzzy and Neuro controller. I am getting good results with Conventional,Fuzzy and Adaptive Fuzzy. But With Neuro controller I am getting distortion/ Harmonics in torque and current waveform after 2.5 Sec.I have used two layer network. Kindly provide the solution.
