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].
