Information

Package Content

Name	Description
ComplexExpression	Set output signal to a time varying Complex expression
ComplexConstant	Generate constant signal of type Complex
ComplexStep	Generate step signal of type Complex
ComplexRotatingPhasor	Generate a phasor with constant magnitude and constant angular velocity of type Complex

Modelica.ComplexBlocks.Sources.ComplexExpression

Information

The (time varying) Complex output signal of this block can be defined in its parameter menu via variable y. The purpose is to support the easy definition of Complex expressions in a block diagram. Note, that "time" is a built-in variable that is always accessible and represents the "model time" and that Variable y is both a variable and a connector.

Parameters

Type	Name	Default	Description
Time varying output signal
ComplexOutput	y	Complex(0)	Value of Complex output

Connectors

Type	Name	Description
Time varying output signal
output ComplexOutput	y	Value of Complex output

Modelica definition

block ComplexExpression 
  "Set output signal to a time varying Complex expression"

  output Modelica.ComplexBlocks.Interfaces.ComplexOutput y=Complex(0) 
    "Value of Complex output";


end ComplexExpression;

Modelica.ComplexBlocks.Sources.ComplexConstant

Information

The Complex output y is a constant signal:

Extends from Modelica.ComplexBlocks.Interfaces.ComplexSO (Single Output continuous control block).
