Feedback Issues in Dynamic Optimisation of a Small-Size Wastewater Treatment Plant
This simulation study presents dynamic optimisation of a small size single basin wastewater treatment plant. The ob jectives are to determine an optimal sequence of aeration/non-aeration times and the corresponding periodical steady state sub ject to minimisation of energy consumption. Based on the optimal tra jectories, two simple feedback rules are proposed that follow from properties of the optimal solution. Simulation results with these simple rules show very satisfactory control performance.
