On the Use of a Truth-space Diagram for Assessing Linguistic Rules

The main objectives of this study were to improve the process of selecting the valid rules and to accurately predict the value of the output. A hot and cold water mixer simulator was used to generate the data. The For the purpose of comparison, the truth calculations for the antecedent and consequent were performed using both the geometric operator and minimum operator. For each operator, different rule sets were obtained by using different threshold values for corroboration and merit. A statistical technique was developed to quantify the delay. In the prediction phase, Kumar's modified prediction technique was compared to the conventional prediction technique used in fuzzy logic. The RMS prediction error obtained from these techniques were calculated and compared.School of Chemical Engineerin
