Neuro-fuzzy control system for temperature control fermentation

The algorithm of management on the basis of indistinct logic is worked out developed and the system of automatic stabilization of temperature of process of a fermentation in the bio-reactor of continuous action is investigated. Results of modeling of the fuzzy controller and assessment of its efficiency in comparison with the traditional proportional and integrated and differential regulator (PID-regulator) are given. For development of the regulator of stabilization of temperature of exothermic process of a fermentation the hybrid technology of adaptive neuro and indistinct system of the conclusions - ANFIS is used. The developed indistinct regulator provides requirements to stabilization of temperature of fermentative system at restriction on operating influence. Results of researches showed that introduction of the offered system will allow to increase the accuracy of maintenance of the set temperature concerning the PID-regulator for 2,1% and to cut a peak expense of a coolant on 43%. The robastnost to indignations on temperature of cooling water and compensation of a thermal emission of process at restriction on a consumption of cooling water is thus provided and at admissible temperature mismatches in system at a peak thermal emission.
