RTC Window Editor - Member Function Pane

A set of membership functions can be defined for each input and output of the fuzzy logic control algorithm. Each definition has 4 parameters defining a trapezoidal (or triangular) probability function.

The Member functions pane contains the following fields:

Name The name of this input/output function. This must be unique for this input/out function for the current regulator.
Input/output

The choices are:

  • L1 - level at the target
  • RC1 - rate of change of level at the target
  • L2 - the level at the gate
  • RC2 - is the rate of change of level at the gate
  • OUT - the output of the member function
Bottom left The bottom left value of the trapezoidal probability function for the selected Input/output type.
Top left

The top left value of the trapezoidal probability function for the selected Input/output type.

This value must be greater than the Bottom left one, and must not exceed the Top right one.

Top right

The bottom right value of the trapezoidal probability function for the selected Input/output type.

This value must be greater than Bottom right one.

Bottom right

The bottom right value of the trapezoidal probability function for the selected Input/output type.

This value must be greater to the Bottom left one.
