A new approach to designing control of dissolved oxygen and aeration system in sequencing batch reactor by applied backstepping control algorithm
Abstract
The Wastewater Treatment Plant (WWTP) is a very complex system, due to its nonlinearity, time-variance, and multiple time scales in its dynamics among others. The most important control parameter in a WWTP is the Dissolved Oxygen (DO) concentration. The tracking problem of the DO concentration is one of the most fundamental issues in biological wastewater treatment. Proper DO concentration control is necessary to achieve adequate biological conditions for microorganisms in a WWTP. Aeration is an im-portant, but expensive activity. It is performed using an aeration system, which includes blowers, pipelines and diffusers. This pa-per presents a new approach to designing a nonlinear control system for DO concentration control using an adaptive backstepping algorithm. A model of biological processes and a model of aeration system are applied for control system design. Simulation tests of the control system are performed. Very good control results were obtained. The proposed solution has proved to be effective and computationally efficient.
