NNPC error - S-function block 'untitled/NN Predictive Controller/S-Function' references obsolete level-1 MATLAB S-function 'predopt'.
显示 更早的评论
Hello
I am working with NNPC block in Simulink with my plant model designed as a physical model of Ohmic heater using the Simscape library. The inputs to the NNPC for 'Plant Identification' step is Voltage (input) and Temperature (output). After the training of the NN, I enter the necessary values for the controller. The controller block gives me this error:
"Warning:S-function block 'untitled/NN Predictive Controller/S-Function' references obsolete level-1 MATLAB S-function 'predopt'. Manually review the code and convert to level-2 MATLAB S-function if necessary. For more information, see Convert Level-1 MATLAB S-Functions to Level-2."
Can anyone please help me how to remove this error. Any insights on this issue will be highly appreciated.
Thanking in anticipation.

It seems that the model was initially developed using an older version of MATLAB with a Level-1 S-function, and then it was imported and saved in a newer version. Could you try the following steps? Enter the "NN Predictive Controller" subsystem of the model and remove the "predopt" block. Then, create a new Level-2 S-function block with the following details:
S-function name: predopt
Parameters: You can copy and paste this list of parameters from the Level-1 S-function, as they might be the same.
After replacing the Level-1 S-function with a Level-2 one, try running the model again to see if it works successfully.
I hope this helps!
