Description

Simple Voltage-Frequency-Controller.
Amplitude of voltage is linear dependent (VNominal/fNominal) on frequency (input signal "u"), but limited by VNominal (nominal RMS voltage per phase).
m sine-waves with amplitudes as described above are provided as output signal "y".
By setting parameter EconomyMode=true, Voltage rises quadratically with frequency which means flux,torque and loss reduction for fan and pump drives.
The sine-waves are intended to feed a m-phase SignalVoltage.
Phase shifts between sine-waves may be chosen by the user; default values are (k-1)/m*pi for k in 1:m.
