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: Amplitude of trapezoid to be generated (default value = 1)
rising: Length of rising time of trapezoid to be generated (default value = 0)
width : Length of on state of trapezoid to be generated (default value = 0.5)
falling: Length of falling time of trapezoid to be generated (default value = 0)
period: Length of period of trapezoid to be generated (default value = 1)
nperiod: Number of periods of trapezoid to be generated
an infinite number of periods is being generated if nperiod < 0 (default value = -1)
offset: Offset of trapezoid to be generated (default value = 0)
startTime: Start time of trapezoid to be generated (default value = 0)
Equations:
when pre(counter2) <> 0 and sample(startTime, period) then
T0 = time
counter2 = pre(counter)
counter = pre(counter) - (if pre(counter) > 0 then 1 else 0)
end when
e = offset + (if (time < startTime or counter2 == 0 or time >= T0 +
T_falling) then 0 else if (time < T0 + T_rising) then (time - T0)*e0/T_rising
else if (time < T0 + T_width) then e0 else
(T0 + T_falling - time)*e0/(T_falling - T_width))
