| Abstract: | Ammonia-nitrogen wastewater treatment with three-phase bio-fluidized bed is a kind of complex object with big inertia,non-linear and uncertainty to be controlled.Brief mathematical model is developed.A scheme of fuzzy PD plus I and regular PID switching control is proposed.The simulation results indicate that the control system has large stable margin,quite high control precision,nice transient characteristics and the ability to reject the disturbance.It has smaller static error to step disturbance than fuz... |
