Abstract
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 the
application and performance of Fuzzy like PI Controller to set the frequency of Space
Vector Pulse-Width modualtion (SVPWM) Inverter applied to closed loop speed control of
IM. When the controller is used with current controller, the quadratic component of stator
current is estimated by the controller. Instead of using current controller, this paper
proposes estimating the frequency of stator voltage. The dyanamic modelling of the IM is
presented by dq axis theory. From the simulation results, the superiority of the suggested
controller can be observed in controlling the speed of the three-phase IM.
