【摘要】 大型循环流化床由于其目前还没有一个理想的数学模型，且运行时滞后时间长，影响因素多，传统的PID控制难以满足稳定运行的需要．本文采用现代控制理论一模糊控制，根据现场运行人员操作经验建立控制规则，以期实现大型循环流化床无数学模型的微机在线自动控制．更多还原

【Abstract】 By now, The CFB has not an ideal mathematics model. And its running is influencedby many reasons which are not clear, The traditional controlling way can’t fit the need ofCFB’s running. This limits the development of CFB. Fuzzy Control is a new colltrolling way.It can colltrol the subject according to the worker’s experience on the condition of unknowingthe subject’s mathematics model. This paper use the fuzzy control to control the CFB, sothat the CFB can work automatically with the computer watching and controlling in line.The controlling model was used in the 1 t/h fiuidzed bed of the National Laboratory of CoalCombustion, and the result is expected.更多还原
