Abstract :
A new approach for deadbeat control of a PWM invertor is presented, in which the estimation of the disturbance is carried out with a repetitive predictor instead of a disturbance observer. Taking advantage of repetitiveness of the loads, it gives good performance at lower sampling frequency. Simulations and experiments confirmed the advantages
