摘要： 针对常用的PID轧机辊缝控制系统在补偿轧辊偏心这一周期信号时,会产生很大的稳态跟踪误差,常使偏心补偿失败的问题,应用重复控制基本理论设计了一种新的轧辊偏心补偿系统,这种系统在对轧辊偏心周期信号进行补偿时,具有对偏心补偿信号无稳态偏差跟踪的特点.仿真证明这种轧辊偏心补偿重复控制系统的输出补偿效果非常好,稳态精度很高,远远优于常用的PID控制补偿系统,使偏心补偿控制的成功率大为提高.

Abstract: The conventional PID controller used in roll gap control system may cause great steady-state tracking error when compensating the periodic signal of roll eccentricity, and thus the roll eccentricity compensation often fails. For this reason, a new eccentricity compensation system based on the theory of repetitive control is presented, by which there is no steady-state error when tracking the periodic signal to compensate roll eccentricity. The simulation results show that the new system can respond very well the compensation for roll eccentricity with highly steady accuracy. It outperforms far and away the conventional PID controller system and greatly improves the probability of success of roll eccentricity compensation.
