Hi, you can write fuzzy logic rules and MFs through the M-File code.

I am here giving a sample code for 2 input MFs and 1 output with 9 rules. You can modify this for your case.

function [u]=Standard_FLC(V_mu,V_m)

%Part_I :Member-ship Functions

%Creates a new Mamdani-style FIS structure

a=newfis('optipaper');

a=addvar(a,'input','relvelo',[-1.5 1.5]);

a=addmf(a,'input',1,'n','trapmf',[-1.5 -1.5 -1 0]);

a=addmf(a,'input',1,'z','trapmf',[-0.25 -0.05 0.05 0.25]);

a=addmf(a,'input',1,'p','trapmf',[0 1 1.5 1.5]);

a=addvar(a,'input','velo',[-1.5 1.5]);

a=addmf(a,'input',2,'n','trapmf',[-1.5 -1.5 -1 0]);

a=addmf(a,'input',2,'z','trapmf',[-0.25 -0.05 0.05 0.25]);

a=addmf(a,'input',2,'p','trapmf',[0 1 1.5 1.5]);

a=addvar(a,'output','damper rate',[0 10000]);

a=addmf(a,'output',1,'s','trapmf', [0 0 1800 5000]);

a=addmf(a,'output',1,'m','trimf', [2400 5000 7500]);

a=addmf(a,'output',1,'l','trapmf', [5000 10000 15000 15000]);

ruleList=[ ... 1 1 3 1 1 1 2 2 1 1 1 3 1 1 1 2 1 2 1 1 2 2 2 1 1 2 3 2 1 1 3 1 1 1 1 3 2 2 1 1 3 3 3 1 1 ];

a=addrule(a,ruleList);

FLC_input=[V_mu,V_m];%defining inputs to fuzzy

u=evalfis(FLC_input,a);%evaluating output a.fis

%fuzzy(a)%--- displays the FIS Editor.%

%note it will display FIS editor for %every time step so for 10 sec it will produce 1001 FIS editors.

%mfedit(a)%---- displays the Membership Function Editor.

%ruleedit(a)%--- displays the Rule Editor.

%ruleview(a)%--- displays the Rule Viewer. %surfview(a)%---- displays the Surface View

Hi, yes there is. At first it should be said that it is better to use it without tool box.but if u wanna run it without using tool box you must write its codes yourself

I agree with Mr.Aliraza.. you may find some codes online for that but its advisable, write your own code to answer your problem.

Thank you Mr. Deepak Unaune.

you can write your own code in m-file

also you can make your own GUI

We can share some of our codes with you. Please contact [email protected] in our lab. Explain your problem and he will help you to customize something.

 I could not understand the line FLC_input=[V_mu,V_m];%defining inputs to fuzzy 

in Deepak's given code.

Dear colleagues,

I do NOT have any experience with fuzzy logic. Please don't contact me regarding this matter. However, I will be happy to help with the areas of my expertise.

using fuzzy tools how can we make a M-file.and pass a image matrix to the eval fis in M-file.

 Any ideas to solve this error: "To use 'newfis', you might need: newfis - Fuzzy Logic Toolbox Error in Standard_FLC (line 4) a=newfis('optipaper');"?

Many thanks

I don't know why it is not working

Error is:

Simulink does not have enough information to determine output sizes for

this block. If you think the errors below are inaccurate, try specifying

types for the block inputs and/or sizes for the block outputs.

You may try to design your own FLC and optimize the MFs like this paper posted on https://goo.gl/HrFxnY
