چکیده

A nonlinear anaerobic digester model of wastewater treatment plants is considered. The stabilizability of the dynamic system is studied and a continuous stabilizing feedback, depending only on an online measurable variable, is proposed. Computer simulations are carried out in Maple to illustrate the theoretical results.

Damping Feedback Stabilization of a Wastewater Treatment Plant

This paper considers the problem of stabilizing a wastewater plant using damping feedback controller. The nonlinear model used is the AM1 anaerobic digestion model. The proposed approach consists in using a damping state feedback controller that renders a desired equilibrium stable through feedback. We first construct an approximate dissipative potential function centered at the desired equilib...
