The fuzzy sets R ∼se and I ∼a can be related through a fuzzy relation, say R ∼
, which would allow for the establishment of various degrees of relationship between pairs of resistance and current. In this way, the resistance–current pairings could conform to the modeler’s intuition about the trade-offs involved in control of the armature. Let N ∼ be another fuzzy set having numerous values for the motor speed, say v values, given as
