Multiple Inputs to Neural Network Predictive Controller in Simulink

Is there a way to realize a MISO system in the Neural Network Predictive Controller block of Simulink? I can't find a way to import my NARX-plant-model with 3 inputs and 1 output (Error: "The neural network plant must have 1 input.") . Neither can I do a plant identification using the GUI and my data. The question had been asked several times but there was no answer till now.

Your help is highly appreciated!

I had roughly the same problem as you have now. And, after looking at the example of Neural Network Controller Design, I think I found the solution. I don't know whether my case is the same as you are, because I used NN Predictive Controller.

To solve the issue, you need to make a separate file of your plant model (with inport and outport of course) before you put it in the setting of the controller. But in your model with controller, you keep making the plant model which is the same as the separated one. Hope this will solve yours.

Can you further explain the solution
