For a given fuzzy logic controller, we have the following three fuzzy control rules:

Rule $1$: IF x is A$1$ OR y is B$1,$ THEN z is C$1.$

Rule $2$: IF x is A$2$ AND y is $"!,$ THEN z is C$2.$

Rule $3$: IF x is A$3$ AND y is B$3,$ THEN z is C$3.$

Suppose x$0$ and y$0$ are the sensor readings for linguistic input variables x and y and the following membership

functions for fuzzy predicates A$1,$ A$2,$ A$3,$ B$1,$ B$2,$ B$3,$ C$1,$ C$2$ and C$3$ are given:
