Design of speed controller for three phase induction motor using fuzzy logic approach

Abstract EN

The use of Induction Motor (IM) has been increased becuase of it’s robust construction , 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.
