根据液固流化床粗煤泥分选机的分选原理和分选效果影响因素提出了液固流化床分选粗煤泥的基本自动控制系统和高级自动控制系统,基本自动控制由PID控制实现稳定控制,高级自动控制由模糊控制和PID控制复合控制实现进一步优化控制。

英文摘要：

According to the separation principle of the coarse slime separator with the liquid-solid fluidized bed and the influence factors of the separation effect,the basic automatic control system and the advanced automatic control system of the liquid-solid fluidized bed for the separation of the coarse slime was provided.Base on the automatic control could have a stable control via PID control,the advanced automatic control with the fuzzy control and PID control combination would have a further optimized control.
