摘　　要：为解决APMP制浆废水好氧处理中溶解氧控制过程的严重非线性、时间延迟等问题,以S7-400PLC的APMP制浆废水好氧处理DCS控制系统为例,将前馈专家控制、PID控制、专家反馈控制算法结合起来对曝气池内的溶解氧含量进行控制,根据不同阶段所表现出来的不同特性即溶解氧偏差的实时变化采取不同的专家控制策略,从而使溶解氧浓度保持在要求范围内,获得理想控制效果。In order to solve problems of severe non-linearity, time-delay in aerobic treatment control system for alkaline peroxide mechanical pulping （APMP） effluent, a DCS control system based on S7-400PLC was given as an example. A feedforward control and PID control plus expert feedback system for DO value control were utilized, by which different expert control rules were made according to the derivative of DO error real time change in different stages. So DO consistencies could be kept at the desired level to get ideal control effect.
