预估智能控制系统在污水处理中的应用研究

Intelligent Control System with Predictive Model in Wastewater Treatment

针对污水处理中溶解氧浓度控制具有较大惯性、纯滞后、具有一定不确定性及难以建立精确的数学模型等特点,提出了具有预估功能的智能控制策略,利用Matlab中的Simulink工具,对溶解氧智能控制系统进行了仿真实验,仿真结果验证了该控制策略的鲁棒性和有效性,具有推广应用的价值。

DO is choosed as the control object in wastewater treatment.Because of the complexity,lag,process disturbances,dy- namic,nonlinear,difficult to found exact model in the DO biochemistry process.This paper brings forward control strategy of intelligent with predictive model.At last,it simulates the design model with simulink in MATLAB and gives the simulation re- sults and analyses.The experiments are made to show the effectiveness and robustness of the proposed method.
