摘要：
This paper proposes an improved and robust induction motor drive control method which uses minimal number of sensors, providing only dc-link current measurement as a feedback signal. The proposed dc-link current sampling scheme and modified asymmetrical PWM pattern cancel characteristic waveform errors which exist in all three reconstructed line currents. In that way, proposed method is suitable for high-quality and high-performance drives. Comparison between conventional and proposed current reconstruction method is performed using hardware-in-the-loop (HIL) test platform and digital signal processor (DSP).
