Advanced control system for municipal wastewater treatment plant

Abstract

In this paper a proposal of a predictive control of a wastewater treatment plant was presented. Proposed multilayer control structure is composed of direct access PID controllers and supervisory DMC (Dynamic Matrix Controller) predictive controller. Basic idea of applied multilayer control structure was to use DMC controller to predict and compensate present and future measurable disturbances (flow and load of a crude sewage). Validation of presented approach was performed with use of computer simulations with different disturbance scenarios. The research was based on data obtained from a wastewater treatment plant in Resovia.
