The Voltage Controller component is a simple voltage-controller. The desired rms values of the d- and q-components of the space phasor current in rotor fixed coordinate system are given by inputs $i_{d\,\mathrm{rms}}$ and $i_{q\,\mathrm{rms}}$. Using the given rotor position (input $\mathrm{\phi }$), 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 $y$). They can be used to feed a voltage source which in turn feeds a permanent magnet synchronous machine. Note: No care is taken for current or voltage limiting, as well as for field weakening.
