Intelligence-BasedFusionControlStrategyin AerationProcessofPollutedWaterTreatment

Polluted water treatment involves complicated biological and chemical processes.To overcome the difficulty in controlling the aeration process resulting from the uncertainty of the related parameters,this paper proposes an intelligence-based fusion control strategy for polluted water parameters.It analyzes the key parameters needed to be controlled and the process characteristics of polluted water disposal,discusses the fusion-based strategy of parameter control in polluted water,constructs a model of controller structure,and gives the control algorithm.Based on the control model developed,a simulation experiment is made,which demonstrates that the proposed intelligence-based fusion control strategy is superior to PID in their dynamic and static quality and that the proposed control strategy is feasible and effective.
