Fuzzy logic C++ library

This class allows you to create an object of fuzzy logic type, supports the creation of multiple inputs, outputs, and sets for each of them, as well as the creation of multiple rules. allows defuzzification, and find the current value of the outputs, based on the current value of the inputs, and the defined rules.

Example

#include "Fuzzy_logic.h"

  // Create fuzzy logic object
  Fuzzy_Logic Fuzzy_Machine;

  // Create inputs set objects
  Input *Error = Fuzzy_Machine.create_input();
  Input *Derivate = Fuzzy_Machine.create_input();

  // Create outputs set objects
  Output *Pwm = Fuzzy_Machine.create_output();

  //Set sets to input objects
  Set *Low_Error = Fuzzy_Machine.create_input_set(Error, -1, 0, 1);
  Set *High_Error = Fuzzy_Machine.create_input_set(Error, 2, 10, 20, 100);
  Set *Low_Derivate = Fuzzy_Machine.create_input_set(Derivate, -0.1, 0, 0.1);

  //Set sets to output objects
  Set *High_Pwm = Fuzzy_Machine.create_output_set(Pwm, 100);
  Set *Medium_Pwm = Fuzzy_Machine.create_output_set(Pwm, 50);
  Set *Low_Pwm = Fuzzy_Machine.create_output_set(Pwm, 10);


void setup()
{
  Serial.begin(9600);

  //Create rules
  Fuzzy_Machine.create_rule(High_Error, High_Pwm);
  Fuzzy_Machine.create_rule(Low_Error, Low_Derivate, Medium_Pwm);
}


void loop()
{
  //Set actual values to inputs
  float actual_error = 0.1;
  float actual_derivate = 0;

  Serial.println(actual_error);
  Serial.println(actual_derivate);


  Fuzzy_Machine.set_input_value(Error, actual_error);
  Fuzzy_Machine.set_input_value(Derivate, actual_derivate);

  //Defuzzificación
  Fuzzy_Machine.deffuzy();

  //Get Output
  float Control = Fuzzy_Machine.get_output_result(Pwm);
  Serial.println(Control);
  Serial.println("");
  delay(10000);
}
