Extremum Seeking Method and Its Applications for Operational Cost Minimaization Control of Efflunet Quality for Advanced Wastewater Treatment Process

摘要

In this paper, a cost minimization control of effluent quality has been proposed for pre-denitrification process. Certified cost function that considers every penalty of the plant and converts them to Yen has been appointed to achieve both clean effluent quality and low operational cost. Optimization probelm then, has been solved by the upper level controller incorporating the extremum seeking algorithm to minimize total cost. The effectiveness of the proposed method has been tested by the well accepted, biological wastewater treatment simulator SIMBA 4.1.
