MATLAB: Add_line or connect or other commands.

Question

Hi All,

This might be a simple question but…

I am simulation a rotating machine use the equivalent circuit, and the case has so many resistance to connect different style at each step, so I am trying to connect the up RLC block to the down RLC block (shown in figure) using the "add_line" command.

I have been trying the following line but keep running into an error: add_line('mySys','Ru1/2', 'Rd/1', 'autorouting', 'on')

Error: "Invalid Simulink object name: Ru1/2"

Now both of these ports are different than typical ports. Visually, they are little black circles. Do I need to change the way I identify these types of ports for some reason?

Or, should I have other commands to fix it?

Appreciate any help!!

Thanks!

Answer 1

Check if there is any leading or trailing space in block names and remove the spaces.

If still not working (mysteries Matlab & Simulink...!!!) then try to connect the line using port handles.

 SrcBlkH = get_param('mySys/Ru1', 'PortHandles');
 DstBlkH = get_param('mySys/Rd1', 'PortHandles');
 add_line('mySys', SrcBlkH.Outport(1), DstBlkH.Inport(1), 'autorouting', 'on');
