.Modelica.Blocks.Sources

Information

This package contains source components, i.e., blocks which have only output signals. These blocks are used as signal generators for Real, Integer and Boolean signals.

All Real source signals (with the exception of the Constant source) have at least the following two parameters:

offset Value which is added to the signal
startTime Start time of signal. For time < startTime, the output y is set to offset.

The offset parameter is especially useful in order to shift the corresponding source, such that at initial time the system is stationary. To determine the corresponding value of offset, usually requires a trimming calculation.
