对精馏塔的工艺流程精馏段温度TR和提馏段温度TS控制，以确保塔顶和塔底产品的质量，所设计的解耦控制系统仿真图。(The distillation process, distillation temperature, TR and stripping temperature TS are controlled to ensure the quality of the products at the top of the tower and the bottom of the tower. The simulation diagram of the decoupling control system is designed.)
