Fuzzy Library for Arduino

Library built to embeded Fuzzy Logic Models on Arduino.

Getting Started

Instalation

• Clone this project inside your arduino /library folder

git clone git@github.com:Amimaro/FuzzyLibrary.git

• Or, download the .zip file and extract it

Documentation

• Fuzzy

Main class. Creates an object to start using the other functions.

Fuzzy fz;

• uint8_t createVariable(uint8_t INPUT/OUPUT)

Creates a variable that can be set as INPUT or OUTPUT. Example: speed, temperature...

• uint8_t addTerm(uint8_t variable);

Adds terms to the variable by setting these variable as parameter. Example: for speed, fast, slow; for temperature, hot, cold...

• void addPointsTo(uint8_t term, float p1, float p2, float p3, float p4);

Adds four points to the term. The points are set based on the X axis, p1 and p4 they are pulled to 0 at the Y axis and p2 and p3 are pulled to 1 at the Y axis.

Example: 0, 1, 1, 2 makes a triangle starting at 0 at X and Y axis, the 1's make the vertex of the triangle at 1 on the X and Y axis and the line goes down to 2 at the X axis and 0 at the Y axis.

• uint8_t createRule(uint8_t input_variable, uint8_t input_term, uint8_t output_variable, uint8_t output_term);

Creates the rule of inference for the fuzzy logic. This function works like this: "if input variable is input_term then output_variable is output_term".

• uint8_t setVariableValue(uint8_t, float);

Sets a value to the term of the variable. This value is set based on the X axis.

• float getVariableValue(uint8_t);

Returns the value of the term of the variable.

• float calculate();

Calculate the defuzzified value of the OUTPUT variable based on the rules of inference and the setted values.
