Information

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));
