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 step response after infinite time (default value = 1) riseTime: Rise time of step response to be generated (default value = 0.5) riseTimeConst: Rise time constant of step response to be generated (default value = 0.1) fallTimeConst: Fall time constant of step response to be generated (default value = riseTimeConst) offset: Offset of step response to be generated (default value = 0) startTime: Start time of step response to be generated (default value = 0)
Equations:
e_riseTime = e0*(1 - exp(-riseTime/riseTimeConst))
e = offset + (if (time < startTime) then 0 else if (time < (startTime
+ riseTime)) then e0*(1 - exp(-(time - startTime)/riseTimeConst)) else
e_riseTime*exp(-(time - startTime - riseTime)/fallTimeConst));
