摘要
为保证双机架可逆冷轧机轧制中带钢恒张力,设计了恒张力简单自适应控制系统.该系统含有电流和速度2个内环,这2个内环均采取PI调节器控制;最外环为张力环,采用简单自适应控制器控制.仿真结果表明,简单自适应控制比传统PID控制具有更好的性能.该系统对带钢恒张力控制具有很强的鲁棒性,提高了带钢板厚和板形的精度.
A simple adaptive control system was designed for constant tension of double stand revere cold rolling mill. This system contains two inner loops for current and velocity control using PI regulators; its outer loop is for tension control using simple adaptive controller. Simulation results indicate that the simple adaptive controller has better performances than classical PID control method. The system has stronger robustness for constant force control, and improves the precision about the thickness and shapes of steel straps.
