Simple Current controller
The desired d- and q-component of the space phasor current in
rotor fixed coordinate system are given by inputs id
and iq. Using the given rotor position (input
phi), the actual three-phase currents are measured and
transformed to the d-q coordinate system. Two PI-controllers
determine the necessary d- and q- voltages, which are transformed
back to three-phase (output y[3]). They can be used to
feed a voltage source which in turn feeds a permanent magnet
synchronous machine.
Inputs d and q can be given either as
peak values (useRMS=false) or as RMS
(useRMS=true). The correction by factor √2 is done
automatically. The measured currents iActual[m] are
assumed to be instantaneous values.
Note: No care is taken for current or voltage limiting, as well as for field weakening.
