Simulink Feedforward- Feedback Control error.

I am working on my feedforward-Feedback control system but keep getting an error

"Undefined function 'getNumInputs' for input arguments of type 'struct'." and

"Undefined function 'getRawData' for input arguments of type 'struct'.".

I don't understsand why the errors occurs and which parts that doesn't work. Many thanks for any verification and explanation.
