modelTrapezoidCurrent
Trapezoidal current source of analog electrical library
Extends from Interfaces.OnePort (OnePort partial model of analog electrical library).
Information
The trapezoidal current source is built in bondgraphic technology from a bond graph trapSf element, a 1-junction, and three bonds. A-causal bonds must be used except at the source, because the causality depends on the embedding of the current source in its environment.
Parameters:
I: Amplitude of source current trapezoid (default value = 1 Amp)
rising: Length of rising time of trapezoid to be generated (default value = 0 sec)
width : Length of on state of trapezoid to be generated (default value = 0.5 sec)
falling: Length of falling time of trapezoid to be generated (default value = 0 sec)
period: Length of period of trapezoid to be generated (default value = 1 sec)
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 Amp)
startTime: Start time of trapezoid to be generated (default value = 0 sec)
