Now we define the fuzzy inference rules (Rule Block -1 –RB1) to the first four parameters mentioned in the table no -1 as inputs with the physical quality of the water as output in the following way using Mamdani method Table -2 Output result from the application of IF –THEN rules,with membership function.
Now we define the fuzzy inference rules (Rule Block -2 –RB2) to the next five parameters mentioned in the table no -1 as inputs with the chemical quality of the water as output in the following way using Mamdani method
Table -3 Analyses of water quality output values
Now we define the fuzzy inference rules (Rule Block -3 –RB3) to the parameters, physical and chemical as inputs with the complete quality of the water as output in the following way using Mamdani method
Table -4 Analyses of water quality output values
STEP: 4 Defuzzification :
Defuzzification is processes to get a non fuzzy control action that best represent the possibility distribution of an inferred fuzzy control action [12].
CENTRE OF AREA METHOD
The widely used COA strategy generates the centre of gravity of the possibility distribution of a fuzzy set C .The method gives .
