referenceposition.m

I am doing motion control and I have imported a signal from SPiiPlus MMI Application into .m file to do a simulation

It is a position reference and i need to use that reference position for my simulation

i tried 'From workspace' block, 'Signal from workspace' block and output to the 'scope' block and I am unable to get the desired reference result

My guess is the From Workspace block is missing time values as your variable CH3 only has data values.

I see. If my period is 100sec, is there anyway to insert it in? Or are there a different way to get the position profile?

There are multiple options, see https://www.mathworks.com/help/simulink/slref/fromworkspace.html. Assuming your measurements are equidistant, you could create a time vector with the same size as CH3 and then concatenate both to a matrix the From Workspace block understands.
