A new approach of the vector control of the induction motor using an inverse fuzzy model

This paper describes a novel inverse fuzzy model based rotor flux oriented vector control approach of the induction motor. In order to obtain high performance speed response, rotor flux oriented vector control techniques are usually used to control the torque and flux separately as in direct current machines. The application of fuzzy logic in modeling of uncertainly dynamical systems is in progress; however fuzzy modeling is one of the major topics in the field of modeling of dynamical systems. The authors has made an effort to develop an inverse fuzzy model of the vector control block applied to the induction motor to successfully improve the classical approach of the vector control. For the simulations results, it is shown that the proposed algorithm can successfully find the inverse fuzzy model that approximate the rotor flux oriented vector control block, with a compact number of fuzzy rules and membership's functions.
