| 摘 要： | 针对中小型污水处理厂,归纳出变参数活性污泥系统的状态空间模型,并对系统进行了稳定性分析.然后,利用状态反馈方法改善系统的动态性能,设计并实现了一个模糊控制器,建立了基于模糊控制的控制模型.通过采用simulink图形化工具平台对控制模型进行建模及仿真,仿真结果表明该模糊控制系统,响应速度快,超调较小,能够根据实际需要将溶解氧浓度快速调整在给定的浓度范围之内,满足控制要求.

| Abstract: | Oriented to small or middle wastewater plant,the space-state model of activated sludge system has been set up,and the system stability has been analysed.Then,a fuzzy control has been designed and realized for the enhancement in system dynamic performance with the method of state feedback,and a fuzzy control model has been given.Furthermore,the model has been simulated with graphic tools simulink and the result shows that the fuzzy control system had quick response and less overshot,and it could regulate DO fast to be within a given range according to actual needs. |
