whenevr i use a defined example of the predictive controller it works well in simulink but when i try to use my model as plant model to generate data its showing the following error:
"Error using nnident (line 1608)
Too many return arguments are specified. Specify only one.
Error in nncontrolutil (line 19)
feval(command,varargin{:}); - Show complete stack trace
Error while evaluating UIControl Callback."
I thought the problems might be with my modela and replaced it entirely with the given example of "cstr" model but still the same problem
Then i tried to replace one of the predefined model with mine own but still the same problem persists
Can anyone please help me out here?

For a new Simulink model, Matlab 2019b, in configuration Parameters /Data Import/Export has ticked for default an additional variable “Single simulation output -> out”. A solution is disactivate this option.
All the best
