Adaptivní prediktivní řízení průtočného tepelného výměníku

Abstract

Heat exchange belongs to the class of basic thermal processes which occur in a range of industrial technologies, particularly in the energetic and chemical industry. The process of heat exchange is often implemented by through-flow heat exchangers. It is apparent that for an exact theoretical description of dynamics of heat exchange processes it is necessary to use partial differential equations. Heat exchange is namely a process with distributed parameters. It is also necessary to take into account its nonlinear and stochastic character. In spite of these facts, most of thermal equipment is controlled by digital modifications of PID controllers at present. This paper deals with identification of a static behaviour of a through-flow heat exchanger and a design of an adaptive predictive controller for its control. The proposed adaptive predictive controller was verified by a real-time control of Multifunction Process Control Teaching System (MPCTS) - the Armfield PCT 40.
