在轧机厚度控制中，压力AGC应用广泛，形式多样。但由于缺乏统一的比较标准和系统的研究，给系统设计者对压力AGC形式的选择带来困难。提出了压力AGC的两个评价准则：厚度估计精度和系统动态特性，并对几种典型的压力AGC进行了分析和比较。简要证明了GaugemeterAGC和Dynamic Set AGC是完全统一的，提出了一种新的压力AGC模型。分析表明：该系统具有很好的动静态特性。
The pressure AGC has been very extensively applied to the gaugecontrol in diversified forms. However the system designers have encountered difficulty of how to determine the righ form of pressure AGC for lack of a uniform standard for comparison and systematical research on the subject. In the present paper two criteria are put forward for the pressure gauge AGC, etc, gauge evaluation precision and dynamic characteristics of the system and a few typical pressure AGCs analyzed and compared and a new pressure AGC model built up. Results show that the gauge AGC is completely in agreement with the dynamic set AGC and the system has excellent static and dynamic characteristics.
