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．
Due to the fact that there is no ideal mathematical model for large-scale circulating fluidized bed at present and the lag time is long and the influencing factors are long, the traditional PID control can not meet the needs of stable operation. In this paper, a fuzzy control of modern control theory, according to the operation of field operators to establish control rules, in order to achieve large-scale circulating fluidized bed mathematical model of the microcomputer online automatic control.
