               The fifth input variable is copper, produced by the generating units.
            According to Tables 13.8 and 13.9, the variable “copper” is shown in Fig. 13.7.
               The Motor Technical State is a product of the relationship between the
            input variable and output variable, which compose the pertinence functions
            expressed in the curves of Fig. 13.8.
               After editing the pertinence functions of all variables, the implemented
            rules are arranged in Table 13.7, as shown in Fig. 13.9 for the visualization
