modelVariableResistor
Ideal linear electrical resistors with variable resistances
Extends from ComplexLib.MultiPhase.Interfaces.TwoPlug (Passive component having two ComplexPlugs p and n and NOT using current phasor balance).
Information
The model contains m linear resistors. Resistor no. k connects the branch voltage phasor v[k] with the corresponding branch current phasor i[k] by
R*i[k] = v[k](k=1...m).
All resistors have the same resistance value specified by input signal R.
Attention!!!
To ensure that the phasor domain-based model works in a quasi-stationary
mode, the input signal R may alter only very slowly in comparison
with both the nominal frequency f=ω/(2π) and the dominant
time constant of the phasor domain-based model.
Remark:
It is recommended that the R signal should not cross the zero value.
