针对南水北调中线工程输水距离长、控制建筑物多、无调节水库的特点，对常用的输水渠道反馈控制方式的适用性进行了分析研究。结合中线工程的调蓄小、水位允许变幅小的运行特征，提出了分别采用水位、水量作为被控变量的联合反馈控制方式，并从降低控制难度、提高控制精度出发，提出了嵌套三点控制方式。模拟计算表明，提出的反馈控制方式可以满足中线工程水位控制的要求。

The Middle Route Project of South-to-North Water Diversion is characterized as long water delivery distance, many controlling projects and no regulating reservoir. The applicability of conventional feedback control methods were analyzed and compared. According to the operation characteristics of small regulation-storage capacity and limited water level variation amplitude, the united feedback control mode that uses both water level and water quantity as controlled variables was proposed;and nested 3-point controlling method was put forward from the views of reducing controlling difficulty and improving controlling precision. The simulation calculation shows that the proposed feedback method can meet the demand of water level control of Mid-dle Route Project of South-to-North Water Diversion.
