Abstract :
In this paper, an effective scheme of predictive control of torque and flux is proposed to decrease the torque ripple and reduce the flux locus distortion in whole speed region. In order to obtain good predictive control of torque and flux, and to solve the pure integration problem of the stator flux estimator based on voltage model, a practical improvement is proposed. The simulation and experiment results show that the dynamic and steady performances have been improved much more than the conventional DTC. Finally, all the proposed schemes are realized on an integrated DSP (TMS320C32) hardware system
