**6. Conclusions**

This paper focuses on the correction of the field-oriented inaccuracy by a model predictive method in induction machine drives, including the base speed region and fieldweakening region. The inaccuracy of the field-oriented control will lead to the actual flux variation, which could be larger or smaller than the reference value. Furthermore, the flux level variation will decrease the output torque and degrade the dynamic performance and current control regulator, especially in the field-weakening region. Therefore, a q-axis and d-axis current predictive method-based correction method for the field-oriented angle is proposed in this paper. To easily realize the proposed method in real-time, the data, such as the current, voltage and velocity used in MPC, are stored in the RAM of the DSP. The effectiveness of this approach is verified by simulations and experiments on a 7.5 kW induction machine setup.
