modelpulseSf
Pulse flow source of the Modelica bond graph library
Extends from Interfaces.ActiveOnePort (Partial model invoking one bondgraphic connector).
Information
The pulse flow source is an active OnePort element. It inherits the effort and flow variables from the active OnePort. The pulse flow to be generated is modeled as a set of five parameters.The flow source has its causality stroke at the source.
Potential variables: e: Bondgraphic effort variable f: Bondgraphic flow variable, normalized positive for flows out of the model Parameters: f0: Amplitude of pulse to be generated (default value = 1) width: Percentage of period in on state (default value = 50) period: Length of period of pulse to be generated (default value = 1) offset: Offset of pulse to be generated (default value = 0) startTime: Start time of pulse to be generated (default value = 0)
Equations:
when sample(startTime, period) then
T0 = time
end when
f = offset + (if time < startTime or time >= T0 + T_width then 0 else f0)
