2.6.4 GAUGE ERROR FEED-FORWARD
In Gauge Error Feed-Forward, GEFF, instead of waiting for an error to appear on the outgoing side of the mill and correcting for it, as in GEFB, the feed-forward control measures the gauge error on the ingoing side and uses the ingoing error to form the basis of control. The measured ingoing gauge error is delayed in a feed-forward store according to the transport distance of the measuring gauge to the roll bite and the ingoing strip speed. The gauge error is retrieved from the feed-forward store prior to actual arrival of the strip element, which was previously measured. The timing, or phase advance, of the retrieval of the data from the feed-forward store depends on the response time of the RFCs and the time constant of the measuring gauge. An additional lead term may be of benefit as the RFC performance depends on the frequency of the disturbance. The delayed ingoing gauge error is scaled by the material to mill stiffness ratio to predict th

2.6.4测量误差前馈
中径误差前馈， GEFF ，而不是等待一个错误出现在即将离任的一侧轧机和纠正的，因为在GEFB ，前馈控制措施的评估误差对ingoing方和使用ingoing错误为基础的控制。
测量误差是ingoing衡量推迟前馈存储根据传输距离的测量指标的辊咬和ingoing地带速度。该指数误差取自前馈商店实际抵达前的条元，这是以前衡量。
的时机，或逐步推进，检索数据的前馈存储取决于响应时间的RFCs和时间常数的测量指标。另外一个可能会导致长期受益的符合RFC的性能依赖于频率的干扰。延迟判断错误ingoing规模的材料轧机刚度比预测的差距，需要修改某一指标的变化。 GEFF只适用于当RFCs的位置控制。示意图前馈控制见下表
