  1. (1) centroid - calculates the output set (OS) area center generated in the inference stage and determines its projection on the x-axis, that is the control output value.
  2. (2) bisector - exact position that splits the output set into two equal areas.
  3. (3) mom (Middle of Maximum) - it performs the arithmetic mean of all maximum values of the OS.
  4. (4) lom (Largest of Maximum) - considers the greatest among all the maximum values of the OS.
  5. (5) som (Smallest of Maximum) - considers the lowest among all the maximum values of the OS.
