Fuzzy Logic

[aliraja]

Hello,

I am developing a fuzzy logic system in Labview.

In the fuzzy system designer, test system tab, below the surface plot, we see the following drop down menus

"Number of input 1 samples"

"Number of input 2 samples"

Kindly tell what are these? as no information about them is given in PID and Fuzzy Logic Toolkit User Manual

Secondly no informaotion about the surface viewer is given

What does the different colors in it mean, and how to analyze the surface viewer plot for two input and one output sample?

Looking forward for your help

Regards,

Ali

The Test System tab on the Fuzzy System Designer is used to test if you membership functions and your rules behave as expected. The Graph shows the relationship between two variables that you can select and the way it tests is by generating several points equally spaced on the selected variable range and evaluating each point (variable1, variable2) on the system, which behaves like a function.

On chapter 7 of the manual (http://www.ni.com/pdf/manuals/372192d.pdf) describes the process and page 7-20 and 7-22 shows the graph for two variables. Although, I do agree we are missing a session that describes the "Test System".

The number of input samples 1 and 2 allow you to make the number of points for each variable more 'dense', if you increase the number of points in each control. Keep in mind that more points means more time to generate the test function.

Hope this helps.
