-
The predictive fuzzy-logic based powder coating system has four application variables as inputs and one output variable, powder deposition (grams)
-
Design of Experiment (DOE) was used to investigates the effects of different combinations of the application variables on powder deposition
-
Response surface method was used to search for the optimal value of powder deposition and to construct the response surface plots of the four application variables
-
The predictive fuzzy-logic model was designed to replicate the behaviour of the response surface plots given similar experimental conditions

Figure 3 illustrates the design methodology
