摘　　要：对建立的板带轧机自动厚度(AGC)混沌系统数学模型进行了混沌特性分析。采用自抗扰控制(ADRC)方法设计了轧机厚度混沌系统自抗扰控制器,并进行了仿真研究。结果表明,所设计的ADRC控制器能够有效控制系统中的混沌和干扰,控制过程快速,稳态误差小,具有较好的鲁棒性。The chaotic characteristics of the established mathematical model of the automatic thickness(AGC)chaotic system of the strip mill are analyzed. The active disturbance rejection controller(ADRC)method is designed for the rolling mill thickness chaos system, and the simulation research is carried out. The results show that the designed ADRC controller can effectively control the chaos and disturbance in the system, and the control process is fast. The steady-state error is small and has good robustness.
