摘　　要：曝气是污水生化处理的最重要环节,针对污水组份不确定性导致的控制难题,探讨了曝气过程控制的仿人智能策略。剖析了被控过程的控制难点,论述了曝气过程的控制论特性,对控制策略作了对比研究,构造了基于仿人智能的工程控制算法。以具有滞后的惯性过程模型为例,仿真相应的对比研究验证了仿人智能策略在上升时间、调整时间、是否超调与稳态控制精度等方面的良好控制品质。仿真研究结果表明,提出的仿人智能控制策略是可行与有效的。Aeration is the most important part of the biochemical sewage treatment. Aiming at the control difficulties caused by the uncertainty of sewage components, the human simulated intelligence strategy for aeration process control is investigated. The control difficulties of the controlled process are dissected, the cybernetics characteristics of aeration process are expounded, the control strategies are compared and studied, and the engineering control algorithm based on human simulated intelligence is constructed. Taking the inertia process model with time lag as example, relevant comparison research is simulated, the good control quality in many aspects, e.g. rising time, adjusting time, whether overshoot or not, and static control accuracy, etc. , of human simulated intelligent strategy is verified.
