"It turns out that the derivative of the Error is equal to negative derivative of Input, EXCEPT when the Setpoint is changing. This winds up being a perfect solution. Instead of adding (Kd * derivative of Error), we subtract (Kd * derivative of Input). This is known as using “Derivative on Measurement” See more This modification is going to tweak the derivative term a bit. The goal is to eliminate a phenomenon known as “Derivative Kick”. The image above illustrates the problem. Since error=Setpoint-Input, … See more The modifications here are pretty easy. We’re replacing +dError with -dInput. Instead of remembering the lastError, we now remember the … See more Here’s what those modifications get us. Notice that the input still looks about the same. So we get the same performance, but we don’t send out a huge Output spike every time the Setpoint changes. This may or may not be a big … See more " - Derivative kick correction

WebBut the task is simplified with the advice given above. Derivative is most useful when applied to lag dominated, higher ordered processes (with or without dead time). When tight control is important, PID is worth pursuing. It can reduce IAE … WebMar 5, 2024 · In other words, there is no sensible way to assign a nonzero covariant derivative to the metric itself, so we must have ∇ X G = 0. The required correction therefore consists of replacing d / d X with. (9.4.1) ∇ X = d d X − G − 1 d G d X. Applying this to G gives zero. G is a second-rank tensor with two lower indices.
