本文对绝热式合成氨反应器,提出一种双线性简化模型。模型的建立是通过原始非线性分布参数模型的正交配置和双线性近似。仿真结果表明,这种双线性模型的近似精度比线性模型高得多。文中还进一步提出了降阶的变参数双线性模型。本文的工作将为探讨合成氨反应器控制系统设计的新途径提供帮助。
In this paper, adiabatic ammonia reactor, a bilinear simplified model. The model is established by orthogonal configuration and bilinear approximation of the original nonlinear distribution parameter model. The simulation results show that the approximate accuracy of this bilinear model is much higher than that of the linear model. The paper also further proposed a reduced-order bilinear model with variable parameters. The work in this paper will help to explore new ways to design a control system for ammonia reactor.
