Linguistic rules (25 maximum) enable experts' know-how to be transcribed using
conditions/conclusions such as: If…Then…
b The definition of a rule is made easier by selecting the input parameters (3 per
rule).
b By assigning one of the possible linguistic terms to each input.
b By defining the outputs affected by this rule (2 per rule) as well as the associated
linguistic terms.
The fuzzy function is easily debugged using the setup and debug screen, especially
simplified by the possibility of simulating the operation offline.
Offline simulation
Once the parameter entry screens have been completed, it is possible to perform the
fuzzy function operation offline. The debug screen offers the possibility of:
b Forcing values for the various input variables.
b Starting the simulation using the “Start” key.
The results achieved are:
The values which will be applied to the outputs in normal operation.
The percentages obtained under the various rules.
Debug in online mode
In online mode the debug screen enables:
b Display of the state of the I/O.
b Access to the involvement percentages obtained under the various rules.
It can also:
b Force the inputs for testing precise operating points.
b Change to manual mode to apply predetermined values on the outputs.
b Change the operating mode: on request, or continuously by defining a period of
activation.
This software extension enables standard functions offered by PL7 Micro, PL7 Junior
and PL7 Pro software to be extended into the domain of fuzzy logic.
It comprises:
b A set of 3"1/2 disks.
b A multilingual user manual (English, French and German).
