摘　　要：为了进一步液压机压下系统控制精度,设计了一种基于带有极大值微扰微粒群优化方法(TCFPSO)改进PID的双辊薄带液压机压下系统控制优化方法。利用AMESim与Matlab联合仿真方式对其实施验证。研究结果表明:对系统设置扰动件后,常规PID控制使辊缝振幅增加值1.13 mm;TCFPSO-PID使辊缝振幅仅0.85 mm,明显增强抗干扰性能,达到更精确的纵向厚度控制效果。采用PID算法得到的缝宽误差为1.2 mm,通过TCFPSO-PID算法获得缝宽误差为1.08 mm,可以有效地减小带材纵向的厚度偏差。该研究对拓展轧机工作过程中调控精度具有一定的意义,尤其是针对薄板制造起到推进作用。In order to further improve the control accuracy of casting and rolling mill's pressing system,a control optimization method for two-roll thin strip casting and rolling mill's pressing system based on improved PID with maximum perturbation particle swarm optimization(TCFPSO)was designed.The co-simulation method of AMESim and Matlab is used to verify it.The results show that the amplitude of roll gap is increased by 1.13mm by conventional PID control after the disturbance is set in the system.TCFPSO-PID makes the amplitude of roll gap only 0.85mm,which significantly enhances the anti-interference performance and achieves more accurate longitudinal thickness control effect.The seam width error obtained by PID algorithm is 1.2mm,and the seam width error obtained by TCFPSO-PID algorithm is 1.08mm,which can effectively reduce the longitudinal thickness deviation of the strip.The research has a certain significance for expanding the control precision of rolling mill,especially for the manufacture of sheet metal.
