Trying to simulate NLARX model in Simulink throws an error

7 views (last 30 days)
I'm trying to use a NLARX model (NL3 below) i constructed inside matlab using the system identification toolbox and the train_id iddata object. I copied the simulation template from the example in this source: https://www.mathworks.com/help/ident/ug/simulating-identified-model-output-in-simulink.html#mw_0e864f8b-d79e-49f5-b8b4-685762bccc6e
I keep getting the error:
Failed to evaluate mask initialization commands.
> Caused by: Output argument "PortNo" (and possibly others) not assigned a value in the execution with "idslmodels.nlarx.addCustomRegressors" function.
whenever i try to run a single simulation and i don't know what i'm doing wrong. The model use the past 60 inputs to produce an output and i'm using a vector of 60 values as an initial condition.
Can anyone please help me? Thanks!
