The use of Induction Motor (IM) has been increased becuase of it’s robustconstruction , simple design , and low cost . This paper presents a methodology for theapplication and performance of Fuzzy like PI Controller to set the frequency of SpaceVector Pulse-Width modualtion (SVPWM) Inverter applied to closed loop speed control ofIM. When the controller is used with current controller, the quadratic component of statorcurrent is estimated by the controller. Instead of using current controller, this paperproposes estimating the frequency of stator voltage. The dyanamic modelling of the IM ispresented by dq axis theory. From the simulation results, the superiority of the suggestedcontroller can be observed in controlling the speed of the three-phase IM.
