Anaerobic Digestion Process Control Using a Data-Driven Internal Model Control Method

Anaerobic digestion processes offer the possibility for wastewater treatment while obtaining a benefit through obtained biogas. This paper aims to continue effort adopt data-driven control methods in case of anaerobic processes. The proposes data-based Internal Model Control approach applied an process. deals extensively with issue choosing reference model and proposing engineering this issue. also addresses verifying robust stability, very important aspect considering uncertainties that characterize bioprocesses general. proposed is validated numerical simulation using Digestion No. 1. During validation solution, main operating conditions were analyzed, such as setpoint tracking performance, rejection disturbance generated by variations influent concentration, effect measurement noise on controlled variable.
