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 ,提出用逆系统控制方法解决具有非线性多变量特点的气固流化床密度控制问题 ,建立了相关数学模型 ,介绍了流化床密度逆控制系统和方法 。On the basis of analysis and research on a controlled objects characteristic for coal preparation with air dense medium fluidized bed, a inverse controlled method is putted forward to use as the density control of fluidized bed, which has non linear and multi variable characteristics. Several mathematics models are established. This paper introduced the inverse controlled system and method, and got a high control precision.
