不论是厚度自动控制系统(AGC)还是辊缝自动位置控制系统(APC),都是用在每个控制周期输出适当的控制电压u的方法使直流电机驱动的压下系统完成所要求的辊缝调节量δs,这就需要找出使压下系统能以最短的时间准确地达到要求的辊缝调节量与其控制电压之间的关系曲线,通常称为速度整定曲线。一般来说,不同的轧机有不同的速度整定曲线。 一、速度整定曲线的确定方法 计算机控制系统中应用的速度整定曲线一般都采用如图1所示的折线形式。在图1中,
Both the Automatic Thickness Control (AGC) and the Automatic Position Control (APC) roll gap control system use the method of outputting the appropriate control voltage u per control cycle to allow the DC motor-driven press system to complete the required roll gap Adjustment amount δs, which need to find out so that the press system can accurately meet the requirements in the shortest amount of adjustment of the roll gap and its control voltage curve, usually called the speed setting curve. In general, different mills have different speed setting curves. First, determine the speed setting curve Computer control system used in the speed setting curve are generally used as shown in Figure 1, the polyline. In Figure 1,
