The error message suggests that the input arguments to your S-Function or Simulink model are expected to be fuzzy inference systems, but the inputs you are providing are not in the correct format.This error can occur if you have used a fuzzy logic block in your Simulink model, even if you are not explicitly using a fuzzy inference system. It is possible that the fuzzy logic block is expecting inputs in the form of fuzzy sets or fuzzy rules, which are not being provided by the inputs to the block.
To resolve this error, you are required to check the configuration of any fuzzy logic blocks in your model and ensure that the inputs used, are in the correct format. Additionally, you can check the inputs and outputs of your S-Function and make sure they are being passed correctly and in the expected format.
I hope this resolve the issue,
Thanks and regards,
