【 摘 要 】
In this paper, the influence of PI controller on hydraulic looper control was analyzed, especially the effect of proportional coefficient KP and integral action time. The PI controller can adjust the stock and tension of the strip according to the deviation between actual value and set value. At the same time, the PI controller has many parameters, such as proportional coefficient, integral action time. The effect of parameters on the output of PI controller was analyzed and tested by programming. The influence law of proportional coefficient is that with increasing the proportional coefficient, the output of PI controller increases and the trend is significant. And the influence law of integral action time is that as the integral action time increases, the output of PI controller decreases. At first, the trend of decrease is remarkable and then weak. This analysis can be used to deepen the understanding of PI controller, then give a positive effect on hydraulic looper control in hot strolling mill, to get an efficient and effective controlling result.
