dc.description.abstract | This work presents a nonlinear model predictive control scheme with a novel structure
of observers aiming to create a methodology that allows feasible implementations in industrial
anaerobic reactors. In this way, a new step-by-step procedure scheme has been proposed and tested
by solving two specific drawbacks reported in the literature responsible for the inefficiencies of those
systems in real environments. Firstly, the implementation of control structures based on modeling
depends on microorganisms’ concentration measurements; the technology that achieves this is not
cost-effective nor viable. Secondly, the reaction rates cannot be considered static because, in the
extended anaerobic digestion model (EAM2), the large fluctuation of parameters is unavoidable. To
face these two drawbacks, the concentration of acidogens and methanogens, and the values of the two
reaction rates considered have been estimated by a structure of two observers using data collected by
sensors. After 90 days of operation, the error in convergence was lower than 5% for both observers.
Four model predictive controller (MPC) configurations are used to test all the previous information
trying to maximize the volume of methane and demonstrate a satisfactory operation in a wide range
of scenarios. The results demonstrate an increase in efficiency, ranging from 17.4% to 24.4%, using as
a reference an open loop configuration. Finally, the operational robustness of the MPC is compared
with simulations performed by traditional alternatives used in industry, the proportional-integral derivative (PID) controllers, where some simple operational scenarios to manage for an MPC are
longer sufficient to disrupt a normal operation in a PID controller. For this controller, the simulation
shows an error close to the 100% of the reference value | es |
