lyapanovPID.slx

Hello,

I'm trying to simulate a lyapunavPID controller. I used the neural network in 3 identical blocks to be responsible for the PID parameters.

In Simulink, I got the error '' Error in default port dimensions function of S-function 'lyapanovPID/NND/NNE'. This function does not fully set the dimensions of output port 2". I tried to specify the dimensions myself in the "Data Edit," and also I tried the "Signal Specification" block, but still, I'm getting this error.

I attached the Simulink file. I'll be grateful if anyone can help me how to solve this problem.
