Abstract

This paper presents the application of adaptive decentralized PI controller to nonlinear activated sludge wastewater treatment plant (WWTP). Tuning of WWTP is a challenging task due to the variation and the high uncertainty of the parameters. Thus, a simple tuning method is applied in satisfying straighten effluent quality and hence optimizing the nitrogen removal of the plant. The PI controller parameters are adjusted directly by updating algorithm developed based on adaptive interaction algorithm theory. It was observed that the decentralized PI with approximate Frechet tuning algorithm offers an attractive tuning task for multivariable WWTP with improvement in energy saving and effluent violations of Benchmark Simulation Model No. 1.
