摘　　要：介绍复杂控制回路的组成、各放大系数的确定方法以及调节器正反作用的确定方法。以某石化企业轻汽油加氢醚化装置中的串级控制、分程控制和比值控制回路为例,对它们进行了设计与分析。The composition of complex control loops,the determination methods of amplification coefficients and regulator＇s positive and negative effects were introduced. Taking the cascade control loop,split control loop and proportional control loop in the hydrogenation etherification device as an example,their control operation was designed and analyzed.
