Modelica.ComplexBlocks.Sources.ComplexExpression

Set output signal to a time varying Complex expression

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

Connectors

Modelica.ComplexBlocks.Sources.ComplexConstant

Generate constant signal of type Complex

Information

The Complex output y is a constant signal:

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

Parameters

Connectors

Modelica.ComplexBlocks.Sources.ComplexStep

Generate step signal of type Complex

Information

The Complex output y is a step signal (of real and imaginary part):

Extends from ComplexBlocks.Interfaces.ComplexSignalSource (Base class for continuous signal source).

Parameters

Connectors

Modelica.ComplexBlocks.Sources.ComplexRotatingPhasor

Generate a phasor with constant magnitude and constant angular velocity of type Complex

Information

The output y is a complex phasor with constant magnitude, spinning with constant angular velocity.

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

Parameters

Connectors

Modelica.ComplexBlocks.Sources.ComplexRampPhasor

Generate a phasor with ramped magnitude and constant angle

Information

The output y is a complex phasor with constant angle and a ramped magnitude.

In case of useLogRamp == false the magnitude ramp is linear:

In case of useLogRamp == true the magnitude ramp appears linear on a logarithmic scale:

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

Parameters

Name	Description
magnitude1	Magnitude of complex phasor at startTime
magnitude2	Magnitude of complex phasor at startTime+duration
useLogRamp	Ramp appears linear on a logarithmic scale, if true
phi	Angle of complex phasor [rad]
startTime	Start time of frequency sweep [s]
duration	Duration of ramp (= 0.0 gives a Step) [s]

Connectors

Modelica.ComplexBlocks.Sources.LogFrequencySweep

Logarithmic frequency sweep

Information

The output y performs a logarithmic frequency sweep. The logarithm of frequency w performs a linear ramp from log10(wMin) to log10(wMax). The output is the decimal power of this logarithmic ramp.

For time < startTime the output is equal to wMin.

For time > startTime+duration the output is equal to wMax.

Extends from Modelica.Blocks.Interfaces.SO (Single Output continuous control block).

Parameters

Name	Description
wMin	Start frequency
wMax	End frequency
startTime	Start time of frequency sweep [s]
duration	Duration of ramp (= 0.0 gives a Step) [s]
