Figure 8From: Intelligent automation and IT for the optimization of renewable energy and wastewater treatment processesOverall performance of the evaluated substrate mixes during optimal control. Figure 8 shows the evolution of the objective value for an algorithm test of the NMPC over a simulated period of 100 days. The individual points (squares) plotted in Figure 8 represent the simulations performed in the constrained optimization problem over the prediction horizon.Back to article page
