Abstract :
Pressure controlled object of distilling tower is complicated, has more effective factors and strong interference, its modeling is difficult. so normal control algorithm can´t control it with satisfactory quality. To overcome this difficult, a kind of genetic fuzzy algorithm is put forward. While fuzzy logic Mimics the human´s imprecise reasoning, the genetic algorithm mimics the evolution of the nature, an optimum point always can be found by the genetic fuzzy algorithm. Experimental result proves that, even through there is strong interference, the algorithm still can ensure actual pressure value to fellow the given pressure value quickly and steadily.
