I am trying to make this motor follow a sine wave however the downward slope of position won't match upwards. For example, it will follow the sine wave from 0 to 1 but will not follow closely enough from 1 to 0. I believe it has something to do with the motor block but I'm not sure. Run the program then look at scope 5 for position compared to sine wave. Thanks for any help in advance.

Hi,
It seems the model tracking the input signal properly for a low frequency sine wave input(5 Hz). I believe the control-loop needs to be tuned.
