Hi there,
I'm encountering this problem for the first time, also i'm new to MATLAB & SIMULINK so please any help will be appreciated.
I'm trying to use NN to control the acceleration of a 1/2 car model, so that i used "NN predictive controller" block as shown and identified the NN plant. But when I run the si,ulation it gives this error:
Whatever i tried it just wouldn't work and I'm not understanding what should I do?

I fixed my error after going back over some documentation
http://www2.cs.siu.edu/~rahimi/cs437/slides/nnet.pdf
And the variable that altered it for me was No. Delayed Plant Input. Mine never worked if it was 1 so I changed it to 2.
I also used the training function trainbr when training my parameters.
Sorry it's not a technical answer, but that's what helped me :)
