Abstract

In this paper, analysis and implementation of two schemes for current control based on space vector modulation are proposed. A novel current control for vector control of induction motor is presented. In which, the set of space voltage vectors are determined according to the stator current error in stator reference frame. An off line switching table based on software implemented comparator for minimizing this error has been implemented. Hence, optimal voltage vectors can be obtained from the inverter by using switching table based on angular coordinate. On the other hand, a modified predictive current controller based space vector modulation is proposed. In this technique, the space voltage vectors which are required to minimize the motor current error are calculated using a discrete motor model every sampling time. The proposed approach incorporates a modified conventional predictive current control with a new approach for reducing current ripples and decreasing the switching frequency. Simulation and experimental set-up results show the advantages and good performance of the two new modulation methods.
