SUMMARY

• Fuzzy rules can be developed verbally to describe a controller.

• Fuzzy sets can be developed statistically or by opinion.

• Solving fuzzy logic involves finding fuzzy set values and then calculating a value for each rule. These values for each rule are combined with a weighted average.
