The block makes it possible to make the current control channels along the axes d and q independent of each other by generating cross-compensation signals. The values of compensation signals are calculated in relative or absolute units [V].
The output signals of the block are calculated by the formulas:
where:
iSq, iSd — projections of the stator current vector on the d and q axes,
Inorm, Unorm — normalizing values of current and voltage,
ωR — stator angular speed,
Zp — the number of motor pole pairs,
Δω — angular field slip velocity,
Lm — the magnetizing inductance,
LσS, LσR — stator and rotor leakage inductances.
Note:
A more detailed description of the model is presented in [1, 2].
