Essay

The thesis is devoted to improvement of the control system of red mad thickening process of alumina production with Bayer process on the basis of fuzzy regulators, creating algorithmic support and improving the information one aiming at increasing the controlled process efficiency. A mathematical model of the controlled process has been created in the paper. A new control method has been developed. A fuzzy control model has been created and fuzzy regulators of the control system have been made on the basis thereof. A principle of measurement has been chosen and a method has been developed for the control of the principal parameter of the controlled process, i.e. the disperse phase concentration in aluminate solution as an information source for the control system. The control system to realise this control method has been developed, made and tested in production process.
