| Abstract |
IPMSM can be operated with its full potential using MTPA and field weakening. Generally, it is not determined which motor is connected to inverter. Therefore, among various methods for MTPA and field weakening, LUT(Look-Up Table) generation test in consideration of inductance change by its saturation is not feasible. In this paper, real-time calculation of current reference is addressed in the full speed region including MTPA and field weakening. Two-dimensional Newton-Raphson method is used to get the solution. |
