摘　　要：分析了CAST污水处理工艺过程,同时建立了溶解氧控制模型。以常规PID闭环系统的阶跃响应曲线分析控制系统不稳定内在原因,给出了专家模糊控制系统设计方法。同时给出了在解跃信号和干扰信号作用下控制系统的仿真和系统的鲁棒性仿真测试。The process of CAST wastewater treatment technology is analyzed and a model of dissolved oxygen control is established. The paper analyses the underlying causes of the instability in the control system by step response curve of Conventional PID closed-loop system and gives the design method of expert fuzzy control system. The article also proposes the jump in the solution of the signal and interference signal under the control system simulation, given the robustness of the system simulation testing. Expert fuzzy control system in biological wastewater treatment system is of the obvious advantages.
