.Modelica_LinearSystems2.ZerosAndPoles.Analysis.isObservable

Information

Syntax

observable = ZerosAndPoles.Analysis.isObservable(zp, method)

Description

Function ZerosAndPoles.Analysis.isObservable checks the observability of a zeros-and-poles transfer function. Therefore, the transfer function is converted into a state space representation which is applied to StateSpace.Analysis.isObservable.

Example

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

  Types.Method method=Modelica_LinearSystems2.Types.StaircaseMethod.SVD

  Boolean observable;

algorithm
  observable := Modelica_LinearSystems2.StateSpace.Analysis.isObservable(zp, method);
// observable = false
