Information

Syntax

zeros = ZerosAndPoles.Analysis.invariantZeros(zp)

Description

Computes the invariant zeros of the corresponding state space representation of a zeros-and-poles transfer function. The output is a complex vector containing the eigenvalues. Note, that the conversion of the transfer function does not result in a minimal state space system. Therefore, also zeros equal to unobservable or uncontrollable eigenvalues will be computed.

Example

  ZerosAndPoles p = Modelica_LinearSystems2.ZerosAndPoles.p();
  Modelica_LinearSystems2.ZerosAndPoles zp=(p+1)/(p^2+p+1);

  Complex zeros[:];

algorithm
  zeros := Modelica_LinearSystems2.ZerosAndPoles.Analysis.invariantZeros(zp);
// zeros = {-1}
