Abstract

This paper describes a hierarchical intelligent integrated control system with three layers: a decision layer, a temperature optimisation and control layer, and a process control layer. An information fusion method is used in the decision layer to determine the operating state of the combustion process in real time. The control strategy includes the temperature optimisation control and process control. The parameters of fuzzy controllers are tuned by a multiple-objective optimisation method with an adaptive genetic algorithm to keep the temperature in the proper range. An intelligent method that combines fuzzy and expert control keeps the gas flow rate and air suction power at the settings.
