系统可看作一个线性系统和一个非线性系统的耦合，线性系统的振荡很弱时，可看作两相对独立系统，或者其中线性系统振荡很强时，系统都将处于锁频状态，

即振荡频率锁在外力的频率或其分频上。但当两系统强弱不相上下时，两振荡强烈影响，系统可以在这三个奇点之间来回跃迁振荡，从而运动复杂化了，这就出现了混沌[4]。
由于在轧制过程中，轧机各参数会有一定的变化，例如，速度会从零升到最大值，当参数值符合一定条件时，就有可能产生混沌现象。2.3偏心示意图、混沌现象仿真图及分析

图3 系统混沌时的相图（ 曲线）
，
(1)由图2知， 随 持续、有界而又不规则震荡，且其震荡是相当稳定的。
(2)由图3知，系统在三个奇点之间来回跃迁震荡，且各种周期轨道，在系统中稠密。
(3)同样由图3知，任何一种周期轨道在区域内都是不稳定的，即在区域内无法找到完全相同的片断[5]。
由此可判断，系统确实进入了混沌。
3 AGC控制系统仿真及分析：
当偏心外扰对于厚度是否出现混沌现象时，AGC对厚度的控制作用会发生很大的变化。
针对以上分析，用Matlab工具软件作仿真。仿真原理图及结果如图4到图5。
长期以来，对于热轧中轧辊偏心的影响，通常使用数字滤波方法将偏心造成的轧制力波动滤去，然后用于反馈。有时也采用专门的偏心控制器，或轧制力内环，厚度外环系统，以消去偏心的影响。我们认为，对于监控AGC系统来说，是个定周期的固定参数的PI调节器结构[1]。在偏心干扰使厚度精度未进入混沌现象时，控制系统处于最优控制器的可能配置。
