Rational Transfer Element G(s)¶
The G(s) element is the general form of a linear transfer element Y(s) = G(s) U(s) where G(s) is a rational function
Transfer function
, an <> 0; m <= n
P-, I-, PT1-, PT2- and PT1T1 elements are special cases of the G(s) element. Since the numerator order m must not be greater than the denominator order n, the element cannot have a derivative behavior. Magnitude and phase response, polar plot and step response depend on the order of the polynomials and the choice of the coefficients.
