Abstract
Acascade feedforward control scheme was designed to address the disturbance caused by changes in feed rate during methanol pre-distillation process, and a PLC control program was written using STEP7 software. The test results showed that the feedforward cascade control scheme can effectively solve the feed interference problem under traditional control methods, and has certain reference significance for the stable control of actual tower and kettle temperature in production sites.
