A ROBUST CONTINUOUS STATE FEEDBACK CURRENT CONTROL FOR INDUCTION MOTOR DRIVES

Faïçal Mnif

   In this paper a current controller based on space voltage vector PWM scheme is presented for induction motor drives. The design consists of a modified continuous state feedback control. This controller guarantees global asymptotic stability for the system as well as robustness against parameters variations and external torque disturbances. Complete theoretical analysis and a simulation example are given to illustrate our approach.
