help understand the step size of the electrical engine dyno example

2 views (last 30 days)
Hello
I still don't get the choice of the step size, with which the torque input data were spaced considering the example's parameters?
does the choosen step size implies seconds or milliseconds?
Generally how do I now which step size between 2 input data does my model require, so that the results are accurate? is it just a step size or does it have a physical logique behind it (like each step size is a second or millisecond).
I don't seem to get the hold of it and I didn't find any helping documentation.
regards,

Click on Modeling Tab --> Model Explorer --> Base Workspace, and then you will see that the sampling time is 1E-5 in seconds. See the screenshot:

yes I know that the fundamental sampling time is 1e-5 but that's not the spacing with which the values of the torque were inputed.
as someone already explained what's the fundamental sample time (https://de.mathworks.com/matlabcentral/answers/2071766-difference-between-control-sample-time-and-fundamental-sample-time-for-foc?s_tid=srchtitle) I'm still missing the time spacing between two input values and its physical meaning, the torque was not inputed every 1e-5s
is the time value 0,11 in the table bellow (second row) equales 0,11s or 0,11*1e-5 s?
