%X 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.
