I have a slight problem with my code.
I have highlighted and explained the flow as well as i can. Please let me know if further clarification is required. The .mcd file is also attached for your reference.
My question: When I look at the values of U_n and PTCU_n, the values seem to keep increasing indefinitely. In theory, PTCU_n should stabilize at 75% when tn_n reaches 6xRTC and not increase any further. I am not sure where I am going wrong.
Any help is appreciated.
Thank you in advance!
Does this make sense?
I reduced the scale of PTCU by a factor of 100, to make it fit on the same scale as the others.
Note that your construct:
is reduced by me to
because the two surrounding expressions are not assigning anything.
Thanks for your response, Luc.
A clarification: The square waveform generator section is designed that way because I am modelling a motor inrush. Hence the two equations surrounding a<--a+1 are to define the spike in current during a motor start.
That aside, this certainly polishes my graph by a lot.
However, the exponential function (U_n) and thereby the PTCU_n function still does not settle at 75%. I am not sure why. With my hand calculation, the model yields the desired answer. But, with my code, it never seems to settle.
Do you think changing the exp to a log function might help?
Thank you, again!
