functiontoTransferFunction

Information

Syntax

tf = ZerosAndPoles.Conversion.toStateSpacetoTransferFunction(zp)

Description

Computes a TransferFunction record

      n(s)     b0 + b1*s + ... + bn*s^n
tf = ------ = --------------------------
      d(s)     a0 + a1*s + ... + an*s^n

from a ZerosAndPoles record represented by first and second order numerator and denominator polynomials. The poles and zeros and the gain k are computed (zerosAndPoles) and are used as inputs in the TransferFunction constructor.

Example

  ZerosAndPoles p = Modelica_LinearSystems2.ZerosAndPoles.p();
  Modelica_LinearSystems2.ZerosAndPoles zp = 1/(p + 3)/(p + 1)

algorithm
  tf:=Modelica_LinearSystems2.ZerosAndPoles.Conversion.toTransferFunction(zp);
//  tf = 1/( s^2 + 4*s + 3 )
