摘　　要：以双机架可逆冷连轧机液压APC(Automatic Position Control—位置自动控制)系统为研究对象,建立了相应的轧机液压APC系统的数学模型,根据轧机液压系统的结构特点,分析了系统中参数不确定的因素,采用了不同的控制方式对参数摄动等的不确定性进行了仿真比较。结果表明采用H∞控制具有更加良好的跟踪特性和对参数摄动的鲁棒稳定性。The hydraulic APC systems of two Tandems reversing cold continuous rolling mill were studied, and the corresponding mathematic models were also established. Some factors of parameters uncertainties were analyzed in hydraulic systems. The different control approaches were adopted to simulate the system uncertainties such as parameters disturbance. Simulation results are presented to illustrate that the H∞ controller can make the control objects possess very good track characteristics and robust stabilization.
