容错控制在浓硝酸高压反应釜中的应用研究

介绍了直硝法生产浓硝酸工艺的关键工序,并分析了对高压反应釜生产进程的质量与产量影响较大的"管道化配料新工艺".针对浓硝生产系统的变参数、强耦合、多变量、高腐蚀、非线性等工艺特征,利用"动态系统故障检测与诊断技术"与"PSBE算法",建立了高压反应釜运行的数学模型,并提出了多个传感器同时发生故障时的容错控制策略,给出了高压反应釜管道化混合装置容错控制方法.

Fault-tolerant Control in the Application Research of The Continuous worked Strong nitric acid Autoclave

This article describes the key procedure of the strong nitric acid production by direct metrification and suggest the new procedure of piping mixing for the autoclave compounding operation which effects the quality and yield of the nitric acid product.Strong coupling,many variables,strong corrosion and non-linearity and so on in the production system of strong nitric acid,it provides fault-tolerant control for the more sense failing at the same time by use of a new technology of the fault detect and diagnosis of the dynamic system and PSBE algorism.It draws strong nitric acid autoclave fault-tolerant control way of the autoclave.
