摘　　要：在考虑轧辊与轧件间的非线性摩擦力和系统延时的基础上,建立了轧机主传动非线性延时控制系统的数学模型,应用自抗扰控制技术设计了轧机主传动非线性延时控制系统。通过仿真与传统PID控制做比较,证明了将自抗扰控制技术应用到轧机主传动控制系统中的有效性和优越性。Mathematical model of nonlinear delayed system in the rolling mill main drive system is derived based on considering nonlinear friction and system delay between roll and rolling, local stability of system and existence of hopf bifurcation are analyzed, simultaneously, delay threshold is obtained, and nonlinear delayed system in the rolling mill main drive system is designed by ADRC technique. The simulation results show that effectiveness and superiority of ADRC applied to displacement delayed feedback system in the rolling mill main drive system by comparing with traditional PID control.
