| Abstract |
This paper proposes a vector control system applied to the current control of a synchronous reluctance motor (SynRM) through a PI controller combined with a disturbance observer (PIDOB). In addition, a conventional PI approach is also presented for comparison purposes. A mathematical model in the synchronous rotating frame of the SynRM is presented. The SynRM presents a non-linear model, as well as parametric variations and coupling between the direct and quadrature axes. Coupled terms are modeled as disturbances. The observed disturbance, obtained through the DOB (Disturbance Observer), is added to the control law as feed-forward action. The experimental results presented confirm the effectiveness of the control strategy, where the PIDOB controller is able to mitigate the coupling between the axes, not transmitting perturbations from one axis to the other. |
