| 摘 要： | 针对SBBR溶解氧系统的纯滞后、非线性、时变性的特点,提出将模糊自适应PID控制器引入到SBBR污水处理系统的曝气过程。采用模糊控制规则,根据控制系统偏差及偏差变化率的大小,自动调整PID控制器KP、KI、KD三个参数的大小,以使系统具有更好的控制品质。通过MABLAB仿真,结果表明,模糊自适应PID控制器比传统PID控制器上升时间缩短了37秒、调节时间缩短了95秒、超调量小3.5%且无静差。

| Abstract: | According to the characteristics of delay,nonlinear and time-varying in the dissolved oxygen system for SBBR,this paper introduced the fuzzy self-adaptive PID controller into the aeration process of SBBR system.The controller can adjust the parameters of KP,KI and KD automatically according to the deviation of control system and the deviation changes with the fuzzy control rules,thereby,the control system gets better quality.MABLAB simulation result shows that,compared with the traditional PID controller,th... |
