| 摘 要： | 针对精馏过程内部机理复杂、参数动态变化情况,提出一种基于前馈补偿和模糊PID的提馏段温度串级控制系统,根据提馏段工况的改变,自适应调整主控制器PID参数,同时引入前馈控制,克服系统不可控扰动。结果表明,该系统能够较好地克服各种干扰,稳定提馏段温度,从而达到间接控制精馏产品纯度的目的。

| Abstract: | In view of the fact that the mechanisms of distillation process is complex,and the process pa- rameters change dynamically,a cascade temperature control system based on fuzzy-PID and feed-forward com- pensation is presented.The system can adjust the PID parameters of the master controller and use feed-forward compensation controller to overcome the uncontrollable turbulence according to the change of operating modes of stripping section.The results show that the system can control many kinds of turbulences ... |
