| Abstract:
|
In this paper a generalized net model of pH control system in biotechnological processes is presented. Generalized nets are preliminary proved to be an appropriate tool for description of the logics of biotechnological process modelling, including the opportunity the biochemical variables of considered processes to be described. The apparatus of the generalized nets allows the possibility for optimal process carrying out. Here generalized nets are applied for modelling of pH control outline in biotechnological processes. The GN model permits to be taken into account the value of pH in the bioreactor. Based on that value the GN model determines what solution (base or acid) have to be added to the bioreactor in order to be controlled the pH value in some desired interval.
