In this paper, a simulation study is made for both the vector-convertion model of a squirrel-cage induction motor and vector control system which takes the model as its control object. In the simulation model, many controllers are used and deeply studied, they are classical PID controller, simple fuzzy control, fuzzy controller with integration factor and fuzzy + PI dual mode controller. In the end of this thesis, fuzzy-neural controller application is stressed.
