Ramp effort source of the Modelica bond graph library
Extends from Interfaces.ActiveOnePort (Partial model invoking one bondgraphic connector).
Information
The ramp effort source is an active OnePort element. It inherits the effort and flow variables from the active OnePort. The ramp effort to be generated is modeled as a set of four parameters.The effort source has its causality stroke away from the source.
Potential variables: e: Bondgraphic effort variable f: Bondgraphic flow variable, normalized positive for flows out of the model Parameters: e0: Height of ramp to be generated (default value = 1) duration: Duration of ramp to be generated (default value = 2) offset: Offset of ramp to be generated (default value = 0) startTime: Start time of ramp to be generated (default value = 0)
Equations:
e = offset + (if time < startTime then 0 else if time < (startTime + duration) then (time - startTime)*e0/duration else e0);
