III. FUZZY LOGIC CONTROLLER. Fuzzy logic is a method of rule-based decision making used for expert systems and process control that emulates the rule-of-thumb thought process used by human beings. The basis of fuzzy logic is fuzzy set theory which was developed by Lotfi Zadeh in the 1960s.

A fuzzy logic controller (FLC) is appropriate for systems with high complexity and nonlinearity. FLC is implemented directly on a chemical process simulator in dynamic mode to handle some uncertainty of the system. Also because accurate tuning of the fuzzy membership functions (MFs) is difficult and has an important effect on FLC performance, particle swarm optimization (PSO) is utilized.
