FUZZY CONTROL OF A SEMIBATCH COPOLYMERIZATION REACTOR

This study describes the development of a rule-based fuzzy controller for regulating the copolymer composition (F-1) in a semi-batch solutio n copolymerization reactor. The membership functions, fuzzy ranges for errors and the controller output are defined. A fuzzy rule base has b een constructed relating error to controller output based on the opera tor's knowledge. The performance of the fuzzy controller has been eval uated by simulating the semi-batch copolymerization reactor by means o f a mathematical model. The fuzzy controller developed at one operatin g condition has also been tested for other operating conditions.
