OPTIMAL CONTROL SYSTEM FOR PROCESSES OF LIQUID EXTRACTION
The process liquid extraction was analyzed as a control object and the main parameters that affect the quality and economic aspects of the process of solvent extraction was established. Formulated on the basis of the basic optimization parameters are set in the form of psycho-analytical desirability Harriton private functions, which are combined to form a generalized objective function as single digits quality of the extraction process in the framework formulated optimality criterion. It is established that the objective function has a unique extremum in any mode of operation of the extractor in this range of optimization options, localization is done on the basis of «golden mean» one-dimensional search for the flow of the extractant. The task of optimization is realized on the basis of higher-level control system with the use of industrial information system SCADA using numerical methods and simulation algorithm. Algorithm is implemented in the language of Visual Basic for Applications and is tested on existing object and to give significant positive economic impact.
