8. FUZZY LOGIC

---

Well suited when we can't get an exact mathematical model (like we did with Laplace transforms)

Based on a set of rules, and some fuzzy descriptions about the problem.

We examine each rule, and each set, and then determine how much each rule applies, and then perform an operation as a combination of the rule effects.

The fuzzy logic controller works like the PID before (except it does more)

This methods has been applied to control of servo motors [Li and Lau, 1988].
