摘 要:针对污水处理的非线性、滞后性和不确定性,提出将智能控制中的模糊控制和传统的 PID 控制相结合,使得控制器同时具有模糊控制的强鲁棒性和普通 PID 的优稳定性。通过 MATLAB 模拟表明,相较于传统 PID 控制器而言,模糊 PID 溶解氧控制系统在污水处理过程中具有响应速度快、震荡较小、稳定性好等优点。

Abstract: Aiming at the fact that sewage treatment is nonlinear, large lag and uncertainty, it is proposed to combine fuzzy control in intelligent control with traditional PID control, so that the controller has both strong robustness of fuzzy control and excellent stability of ordinary PID. MATLAB simulation shows that compared with the traditional PID controller, during the sewage treatment process, the fuzzy PID dissolved oxygen control system has the advantages of fast response, small shock and good stability.
