Abstract: The PID control and fuzzy control system could not attain satisfactory performance as the multivariable nonlinear and coupling of the induction motor’s speed regulation system.In order to get better performance,a fuzzy neural network control strategy to the control of the induction motor’s speed regulation system was proposed in this paper.A strategy of controling on-line based on ANN was proposed,by which the rotator speed can be controled accurately.The mathematical model of the induction motor was developed according to the space vector theories.Simulation results show that the good static and dynamic performance and the strong robustness to both variation of parameters and load torque disturbance can be achieved by using the proposed method.
