| Resumo: | [EN] Predictive control of stator currents needs estimating rotor currents since they are usually not measured. Rotor currents influence the future evolution of the stator currents, affecting the predictions needed by the predictive controller. The usual procedure is to estimate the effect of rotor currents on stator current evolution. This is done by adding the prediction error for the past sampling to the actual prediction. In this paper a new estimation method is proposed using the equivalent circuit of the induction machine. Simulation and experimental results are provided using a multi-phase induction machine as a specially demanding benchmark, showing the superiority of the proposal. |
