Проанализированы различные методы фильтрации измеряемых значений параметров технологических процессов, используемые при разработке компьютерно-интегрированных систем управления для ряда объектов производства кальцинированной соды по аммиачному способу. При сравнении рассмотренных методов получено, что метод рекурсивной регрессии позволяет получить более высокую точность идентификации, чем метод стохастической аппроксимации. Для выбранного метода – рекурсивной регрессии выполнено прогнозирование изменений параметров этих процессов с целью оперативного управления ими.
One of major tasks arising up at development of computer-integrated control system for the row of objects of production of the calcinated soda on an ammoniac method with the use of microprocessor-based comptrollers are authentication of mathematical models of control objects and their periodic adjustment on the well-known entry and output parameters of objects. For the decision of tasks of authentication on the well-known entry and output parameters of objects in the article possibility of application of methods of stochastic approximation and recursive regression is investigated at comparing of them to the least-squares method. In the article the different methods of filtration of measureable values of parameters of technological processes are analyzed used for development of computer-integrated control system for the row of objects of production of the calcinated soda on an ammoniac method. It is got at comparison of the considered methods, that the method of recursive regression allows to get higher exactness of authentication, what method of stochastic approximation. For the chosen method - prognostication of changes of parameters of these processes is executed recursive regression with the purpose of operative control by them.
