Experimental identification of Arrhenius equation parameters for control purposes

Popis výsledku v původním jazyce

In the process control area, there are a lot of systems with nonlinear behaviour. Specific case of such nonlinear system is an exothermic chemical reactor. The reactor nonlinearity can arise from different reasons. One of them is the changeable reactionspeed, which depends on the reactants concentration and the in-reactor temperature. The second dependence is described by Arrhenius equation. Knowledge of the Arrhenius equation parameters is a key for correct mathematical model composition and also forsafe and successful control. Some possibilities of the parameters determination are described in the literature. However, they are complicated and not very suitable for online identification of a real process. A new approach developed by the author is introduced in this article. The possibility of reaction rate and its temperature dependence identification from the measured temperature curves is shown. The method of identification including the derivation of all necessary relations is de
