Rotor flux angle calculation block (for systems with direct orientation by flux). The block calculates the sine and cosine of the rotor flux angle in a fixed coordinate system (relative to axis A).
The rotor flux angle θe in a fixed coordinate system is calculated using the following formula:
where:
- θe — rotor electrical angle,
- θR — rotor angle,
- Zp — the number of motor pole pairs,
- ψR — rotor flux linkage,
- TR = (Lm + LσR)/RR — rotor time constant,
- Lm — the magnetizing inductance,
- LσR — rotor leakage inductance,
- RR — rotor resistance,
- iSq — projection of the stator current vector on the q-axis.
The angle measured with respect to the positive axis of phase A is considered positive, counterclockwise.
Прим.: A more detailed description of the model is presented in [1, 2].
