ADAPTIVE pH CONTROL SYSTEM FOR FED-BATCH BIOCHEMICAL PROCESSES

Vytautas Galvanauskas

Abstract


In the paper pH control problems in fed-batch biochemical processes are analyzed. Process mathematical model was based on the first principles and identified using available experimental data. An adaptive pH control system based on gain scheduling approach was proposed. Significant increase in control quality as compared to a standard PI control system was achieved.
