| 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. |

| Keywords: | inverse-control separating density bed height fluidized bed |
