## 1. 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]. ## 1.1 COMMERCIAL CONTROLLERS## 1.2 REFERENCES## 1.3 PRACTICE PROBLEMS |
