| 摘 要： | 以实现好氧三相内循环生物流化床废水处理过程的闭环控制,克服曝气造成能耗大的问题为目的,研究并提出以入、出水的氨氮浓度为输入、输出量的好氧三相内循环生物反应器氨氮废水处理过程的主导数学模型,并针对这种大惯性、大滞后的被控对象,给出模糊PD+I控制方案。用谐波平衡法分析闭环控制系统的稳定性。计算机仿真分析表明系统对不同的扰动信号,能通过经济调整曝气量实现以一定精度,平稳、迅速趋向设定值,具有好的抗干扰能力和控制精度。

| Abstract: | To have ammonia-nitrogen wastewater treatment with the aerobic internal-circulation three-phase biological fluidized bed feedback controlled,and to avoid the excessive blast aeration,the brief mathematical model is presented.The input and output are the ammonia-nitrogen concentration of wastewater-in and wastewater-out respectively.For such object with both big inertia and time-delay, the fuzzy PD+I controller is figured out.The frequency-dorm harmonic balance analysis verifies the stability of the closed-l... |
