A study of AC machine modeling with current controller using matrix vector and dq transformation

AC machines are being used in industry and dq transformation from 3 phase of a, b, c is commonly used to analyze these machines. The equivalent circuits of d and q axis are however generally cross coupled and not simple to analyze. In this study, a modeling technique of AC machine including induction and synchronous motors using matrix vector is proposed and it can explain the AC machine physically. This model does not need the separating process of d and q components. With this technique, the model becomes simple, is easy to understand in physical, and can get the same results with those from the other models. These simulation results of the proposed model are compared with those of other models for the conformation of the proposed method.
