Block
Note: This block is obsolete.
Description
This block computes the phase domain time-varying inductance matrix of a permanent magnet synchronous machine corresponding to the Ld Lq Park transform inductances and rotor angle.
Mask
Parameters
Voltage base [V] | The model base voltage. |
|---|---|
Current base [A] | The model base current. |
Electric frequency base [Hz] | The model base frequency. Note that the base choice must be the same as in the RTE-Drive Phase Domain PMSM block. |
Number of Pair of Poles | The machine number of pole pair. |
Sample Time [s] | The model sample time. |
Input
Lq [H] | Q-axis inductance in the Park referential. |
|---|---|
Ld [H] | D-axis inductance in the Park referential. |
SinCos | The sine and cosine of the rotor electric angle. |
Note: The Ld and Lq value correspond to the Krause Park transformation in which, for positive speed, the q-axis is ahead of the d-axis and the Park transform has 2/3 factor and all positive sign (no negative row).
Output
Lx [pu] | Inverse of the reduced inductance matrix [2x2], which is time-varying. |
