Abstract- This work investigates a si mple d esign of the new P I-Fuzzy Sliding Mo de Controller ( FSMC) f or s peed regulation o f a n in direct f ield-oriented d ual s tar induction motor (DSIM). The fuzzy controller is driven by the error of the s peed, and i t c hange. T he sl iding m ode controller is designed b ased on a p lant m odel. The influence o f d ifferent combinations of t he F LC an d S MC on t he performance control i s i nvestigated an d i llustrated b y som e si mulation results at different d ynamic op erating conditions su ch as sudden change in command speed, step change in load torque and some k ey p arameters d eviation. F inally t he p roposed controller is i nsensitive t o p arameter variations and load disturbances.
