TY - JOUR TI - Advanced induction motor drive control with single current sensor AU - Adžić Evgenije M AU - Porobić Vlado B AU - Adžić Milan S AU - Ivanović Zoran R JN - Thermal Science PY - 2016 VL - 20 IS - 12 SP - 421 EP - 436 PT - Article AB - This paper proposes induction motor drive control method which uses minimal number of sensors, providing only DC-link current as a feedback signal. Improved DC-link current sampling scheme and modified asymmetrical switching pattern cancels characteristic waveform errors which exist in all three reconstructed motor line-currents. Motor linecurrent harmonic content is reduced to an acceptable level, eliminating torque and speed oscillations which were inherent for conventional single sensor drives. Consequently, use of single current sensor and line-current reconstruction technique is no longer acceptable only for low and medium performance drives, but also for drives where priority is obtaining a highly accurate, stable and fast response. Proposed control algorithm is validated using induction motor drive hardware prototype based on TMS320F2812 digital signal processor. [Projekat Ministarstva nauke Republike Srbije, br.
