Abstract

Abstract: Discrepancy-based control (DBC) represents an elegant direct control design concept for infinite-dimensional systems, which is frequently used to control particle formation processes, an important class of operations in chemical engineering. So far, DBC has been applied to continuous layering growth and agglomeration, which have been accounted for by partial differential equations. In this contribution we develop control laws for infinite systems of ordinary differential equations, inspired by DBC. The results are visualized by the application to a continuous agglomeration process involving additional particle breakage. We show how a two-dimensional controller is able to control the industrially relevant Sauter mean diameter of the product particles, resulting in improved performance of the closed-loop system compared to a single control loop.
