污水处理好氧池里DO值的模糊PID控制系统
摘要：
本发明公开了一种污水处理中自动调节控制好氧池DO（溶解氧）值的模糊PID控制系统及方法。包括：DO值采集传感器、PLC控制电路、供电电源电路、变频鼓风机、MATLAB里的模糊PID控制程序、组态王上位机软件组成，本发明能够使好氧池里的DO值控制简便，利用MATLAB的快速进行复杂算法的优势，DO值控制效果最佳，组态王上位机软件直观显示整个控制过程，很好适应污水处理过程中的非线性和多变性特点。
摘要（英）：

The invention discloses a fuzzy PID control system and method for automatically a DO (Dissolved Oxygen) value in an aerobic tank in sewage treatment. The system comprises a DO value acquisition sensor, a PLC control circuit, a power supply circuit, a variable frequency blower, a fuzzy PID control program in MATLAB and Kingview upper computer software. According to the system, the DO value in the aerobic tank can be controlled easily, an advantage that the complex algorithm is rapidly carried out by the MATLAB is utilized, the DO value control effect is optimal, the whole control process is intuitively displayed by the Kingview upper computer software, and the characteristics of nonlinearity and variability in a sewage treatment process are well adapted.
