Design of a fuzzy logic approach for optimization reinforced zirconia depositions using plasma sprayings

This paper presents the application of a fuzzy logic controller and Taguchiʹs design in developing partially stabilized zirconia (PSZ) plasma spraying coatings. In this study, a fuzzy logic controller was used to explore functional relationships between variables, to determine the effect of operating parameter, and to achieve optimal process conditions. In addition, the most relevant input variables are identified through analysis of variance, and implemented in the construction of an appropriate fuzzy logic controller model. perimental results indicate that the combination of Taguchiʹs design and a fuzzy logic controller makes a robust, effective, and efficient approach. A confirmation run of the optimal conditions was successfully carried out and shown to achieve desirable results.
