Abstract :
To reduce torque ripple and achieve higher performance in very low speed range, indirect torque control method is realized in a dual-DSP control platform and improved by considering the influence of the stator resistance variation on the voltage vector output. To compensate the influence, a new MRAS based method is proposed to identify the stator resistance. High performance is achieved at low sampling frequency and switching frequency less than 1000 Hz. Simulation results and experimental results are given to validate this scheme.
