Blocks in series, Simulink

Hello Matlab and Simulink users.

I would like to calculate the number of Transfer Function blocks that better approximate a Transport Delay block.

Of course, I don't want to manually draw all the blocks and try them.

Is there a way to set the number of blocks in series?

Thanks in advance and best regards,

Maria Angela

Also I do not know the science behind what you want to do, but can image you want to try MATLAB commands like "add_block", "add_line" etc. to create a Simulink model by MATLAB code.

Hello, I don't know if I really understand your problem but there is a block named transport delay able to put the delay you want on your signal. Just put -1 on sampling time to pick the one of your simulation and then you can't choose how much time you want to delay your signal ;)

Hello and thanks for your answer.

I know the Transport delay block, but usually a delay can be approximated with a certain number of Transfer Function blocks.

I need to know how many Transfer Function blocks in series do I need to approximate my delay. Of course, I don't want to manually draw all of them after another and check if the approximation is ok and aventually add another one etc, so I was looking for another way to put blocks in series, but I could not find a solution.

Put a variable in input instead of a value? Then load a file with this value.

So then you can compute your latencies.
