Adaptive fuzzy control of MMA batch polymerization reactor based on fuzzy trajectory definition (original) (raw)

In this research an adaptive fuzzy controller was applied to temperature control of a MMA batch polymerization reactor which use jacket temperature error in additional reactor temperature error. However, the desired jacket temperature is affected by noise and disturbance. Therefore there is uncertainty in desired value of this variable. Fuzzy numbers are applied to model this uncertainty and a fuzzy trajectory was achieved for jacket desired temperature. Then a special case of fuzzy controller called generalized Takagi-Sugeno-Kang fuzzy controller, and an adaptation mechanism was designed. Experimental results present the fine performance of this controller in temperature control of solution polymerization of methyl methacrylate.
