摘　　要：针对活性污泥污水处理过程溶解氧浓度(DO)控制的非线性特性,以DO为控制对象、国际评价基准(benchmark)为平台,将PID控制、增益调度控制和一般模型控制(GMC)方法应用于DO控制中,并进行了控制器性能的比较.仿真结果表明,所提一般模型非线性控制方法的性能优于其他两种控制方法,体现出该方法的有效性和优越性.For the non-linear characteristics of dissolved oxygen （DO） concentration control of activated sludge wastewater treaiment process, with DO as a controlled object and the international evaluation benchmark as a platform, PID, gain scheduling and generic model control （GMC） are studied and applied to the DO control, and the performances of these controllers are compared. Simulation results show that the performance of the presented GMC method is superior to those of the other two methods, exhibiting the effectiveness and advantage of GMC method.
