functionTsig_xsig
Calculates Tsig and xsig
Extends from Modelica.Icons.Function (Icon for functions).
Information
Calculates rotor leakage reactance xsig and corresponding time constants Tsig.
If transient order n > 3, the coefficients xm[2:n-2] are assumed to be 0.
A different choice is not meaningful, as long as we only have 2 parameters (complex field-current) to fit.
