This information is part of the Modelica Standard Library maintained by the Modelica Association.

This blocks computes output y as difference of the commanded input u1 and the feedback input u2. Optionally, either input u1 or u2 or both inputs can be processed conjugate complex, when parameters useConjugateInput1 and useConjugateInput2 are true, respectively.

  y = (if useConjugateInput1 then Modelica.ComplexMath.conj(u1) else u1)
    - (if useConjugateInput1 then Modelica.ComplexMath.conj(u2) else u2);

Example parameters:

• useConjugateInput1 = true,
• useConjugateInput2 = false

result in the following equation:

     y = Modelica.ComplexMath.conj(u1) - u2

useConjugateInput1	Value: false Type: Boolean Description: If true, input 1 is processed conjugate complex
useConjugateInput2	Value: false Type: Boolean Description: If true, input 2 is processed conjugate complex
