Gisteresis - program function automation process

In the process of communication with different customers it turns out that not all of them understand the operation of the mechanism and disable the threshold violations in automated systems. To do this, create the article explaining the essence of the hysteresis in automation.

If we imagine that the process variable will be located near the border trip, inevitably will occur the phenomenon of “bounce” (short passages back and forth over the threshold line). To get rid of the system of “bounce” when approaching a boundary line used “dead zone”, “Dead zone” or “hysteresis” (from the Greek hysteresis -. Lag, lag). That is at the intersection of the corresponding threshold violation occurs without delay, and only disappears when crossing the hysteresis band.
