摘要: 在對氣固流化床選煤系統被控對象特性分析研究的基礎上,提出了用逆控制方法解決具有非線性多變量特點的氣固流化床密度和床高的控制問題,建立了相關數學模型,介紹了流化床密度及床高逆系統控制方法,并獲得較好的控制精度.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.
