铝酸钠叶滤过程控制仿真实验平台

铝酸钠溶液精滤工序（叶滤）是氧化铝生产工艺中必不可少的一个重要环节，实现精滤生产过程的自动控制对于提高氧化铝生产的产品质量与生产效率至关重要。叶滤生产过程设备较多，工艺流程复杂，并且控制系统中回路控制和逻辑控制交织在一起。本文设计并研发了由真实的控制系统和虚拟的叶滤过程仿真对象组成的铝酸钠叶滤过程控制仿真实验平台，该平台可以用于叶滤过程的建模、控制、优化等方面的实验研究，特别是为叶滤过程的先进控制、故障诊断、容错控制等方法的深入研究提供了工程化的实验平台，可有效降低现场的调试风险和调试成本。

Simulation experiment platform for sodium aluminates solution filtrating process

Sodium aluminates solution filtrating process is an essential section in the alumina production process.To improve quality of products,automatic control is extensively used and plays an important role in the production chain.However,filtrating process is a complex production process which has a number of equipments to be controlled.The control system of filtrating involves not only logical control but also closed loop control and there is complex interaction between them.To reduce the field test cost and risk efficiently,based on a real control system and a virtual filtrating process object,this paper presents a simulation experiment platform for sodium aluminates solution filtrating process control.The presented platform makes it possible for research on the modeling,control strategy,optimization of the filtrating process,and provides a functional experiment platform for the research of advanced control technique,such as fault diagnosis,fault tolerant control of the filtrating process.
