摘要
污水处理是一个复杂的生化反应过程,难以数学建模.针对其曝气控制过程中参数的不确定性,采用传统PID控制策略难以实现优化控制的问题,文章以DO参数控制为例,提出了基于仿人智能的控制策略对其实施控制.仿人智能控制策略很好地解决了DO参数值波动的控制问题,有效地保证了出水水质和曝气风量的合理控制.文中给出了控制策略、系统结构和控制规则.仿真结果表明了该控制策略的可行性和有效性,系统动、静态品质好.
The treatment of wastewater is a complicated biological and chemical process, which can not be described precisely with a mathematical model. It is almost impossible to get a satisfactory control result when a traditional PID control method is adopted, for the parameters of the activated-sludge process are uncertain. The paper takes DO parameter controlling as an example, and proposes a human-simulated intelligent control strategy to reduce the fluctuation problem of DO parameter. Both the control rules and the structure of control system are presented. The simulation experiments shows that the control effect of activated-sludge process by HSIC is much better than PID control.
