How to set multiple ports for a step input block

Hi all,

Is it possible to set multiple ports for a step input block? I am tying to run two models with PID controller in simulink and I need two different step signals to be used as the set input for both models.

It is troublesome by using two step signal blocks as I need to set the final value of the signals seperately. So how can I set the final value of the two signal in one identical parameter setting GUI? Is it possible?

Please advice. Thank you very much.

Regards

I believe you can use a single Step block, and then for the various parameters (such as the Final Value parameter) you can set a vector, such as

[-1 1]

This will cause the Step block to output a vector signal, and you can demux the signal to get each element (or use the Selector block).

Great answer, thank you so much...By the way, do you know is there any way to reset the value in the step signal block if a certain condition is met in the simulink? Thank you very much.

Hi Teo,

I would use the Relational Operator block and perform the logic myself, if I was doing something like that.

Hope this helps!
