| 中文摘要 |
| 本文介绍了合成氨生产中氢氮比的一种控制方案.几乎所有的合成氨装置对氢氮比的控制都存在一定的问题.因为氢氮比系统是一个超大时滞系统,大时滞系统的控制问题是过程控制中的难题,超大时滞系统的控制更为困难.本文采取无模型控制方法加前馈来解决这一难题,实践证明这一途经是正确的. |
| 英文摘要 |
| A control scheme of H-N ratio in the production of synthetic ammonia was introduced in this paper.Problems in control the H-N ratio exist in almost all devices of synthetic ammonia production,because the system of H-N ratio is a very-large-scale-time-delay system,which is difficult to be controlled.A model-Free Control Method(MFCM) with feed forward is applied to resolve this tough problem.The practice shows that this method works well. |
