Measurement and Control of Density and Height for Gas-Solid Fluidized Bed

    摘要
  • 摘要: 在对气固流化床选煤系统被控对象特性分析研究的基础上,提出了用逆控制方法解决具有非线性多变量特点的气固流化床密度和床高的控制问题,建立了相关数学模型,介绍了流化床密度及床高逆系统控制方法,并获得较好的控制精度.

     

    Abstract: Based on the analysis and research on a controlled object characteristic for coal preparation with air-dense medium fluidized bed, a inverse-controlled method is put forward to solve the density and height control for the fluidized bed. A mathematical model is established. The inverse system control method is introduced, and the results show a high control precision.
