Induction motor is widely used inindustrial applications. But due to its highly non linear behavior its control is very complex. Non linearspeed control techniques are employed to improve dynamic performance of electric drives.Paper describes multi agent based approach to control speed of Induction motor. Design and simulationof Multi Agent System is developed for Indirect vector controlled 3-phase Induction motor. Soft computingtechniques are used for implementation. Three types of controllers: Classical controller (PI), Fuzzy (FLC)& Neural Network ANN) are constitutant of the Multi Agent system. Simulated speed responses parametersviz: rise time, steady state error and overshoot of SIMULINK models are used to make by a fuzzy logic isused to select the best controller from the constituents. %K Induction motor %K Vector control %K Artificial Neural Network (ANN) %K PI controller %K Fuzzy Logic (FLC) %K Multi Agent System (MAS) %U http://airccse.org/journal/ijsc/papers/2311ijsc04.pdf
