Cross-linking compensation block for AM





in the palette on the schematic

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].
