Description
Summary:In this paper, a new predictive direct power control (DPC) technique is presented for the doubly fed induction machine (DFIM). Based on this predictive control, the strategy is able to operate at considerably low constant switching frequencies and allows it to perform a power ripple minimization technique, in order to improve the steady-state and transient response behaviors of the machine. In addition to the control technique definition, this paper includes a conceptual analysis of DPC. On the other hand, to validate the control strategy, it will be experimentally compared to the well-known voltage frequency control, the vector control, and the nonpredictive DPC strategy. The comparison will be carried out in terms of the steady-state behavior and transient response capacity, and it will be shown that the proposed predictive DPC technique allows to obtain the combination of the quick dynamic response of direct control techniques, and the benefits of constant switching-frequency-based control techniques.
