This paper proposes an induction motor drive control method which uses a minimal number of sensors, providing only DC-link current as a feedback signal. The improved DC-link current sampling scheme and modified asymmetrical switching pattern cancel the characteristic waveform errors which exist in all three reconstructed motor line-currents. Motor line-current harmonic content is reduced to an acceptable level, eliminating torque and speed oscillations which were inherent for conventional single sensor drives. Consequently, the use of single current sensor and line-current reconstruction technique is no longer acceptable only for low and medium performance drives, but also for the drives where obtaining a highly accurate, stable, and fast response is the priority. The proposed control algorithm is validated using induction motor drive hardware prototype based on TMS320F2812 digital signal processor.
