The process of penicillin production is characterized by nonlinearities and parameteruncertainties that make it difficult to control. In the paper the development and testing of amultivariable fuzzy control system that makes use of type-2 fuzzy sets for the control of pH andtemperature are described. The performance of the type-2 fuzzy logic control system (T2FLCS) iscompared by simulation with that of a type-1 fuzzy logic control system (T1FLCS) and that of a controlsystem with traditional proportional-integral-derivative (PID) controllers proposed in the literature.The fuzzy controllers are optimized using an ANFIS algorithm. The best results are obtained with theT2FLCS particularly when uncertainties are present in the control system.
