Questions tagged [feedforward]
The control path from input to output with some set transfer function.
What electronic component does this symbol represent?
From a schematic of a feed forward converter.
What is the function of the feedforward capacitor on the LM2596-ADJ?
I'm looking at the LM2596S datasheet and notice that on page 7 (figure 3) it recommends a "feedforward" capacitor for the adjustable variant. The example schematic on page 9 shows a ...
Transient peaks during MOSFET switching (feed-forward)
I am working on a circuit, part of which looks like this: Signal SW is switching the MOSFET on and off such that the nodes ac+ and ac- are shorted (modulated). When SW is high to turn on the MOSFET ...
A forward converter or flyback converter without voltage spikes?
I was thinking of a way to avoid voltage spikes in a flyback converter and I decided to redirect voltage spikes back to the battery, hence dampening the voltage spikes. Will this method work ...
Feedforward Control: Plant's Process vs Disturbance Model
I have a question on Feedforward Control in a control system, in distinguishing a Plant's Process vs Disturbance Model. Say the Plant is a motor driving a wheel of a car. There's a measurable ...
Feedforward from measurable disturbance
Gff is chosen so that it completely cancels the disturbance (Gff = -Gv/P) and Lp < Lv. Is it easier to control if Tp < Tv or Tp > Tv. I am a little bit lost on how to begin here? Should I ...
Can badly tuned Feedforward still decrease following error
Let's say we're trying to control the speed of a motor to 20 revs/sec, and we know that our controller output for that speed is approximately 5. We currently have a Proportional controller to drive ...
The term Feed-forward and its meaning?
I am trying to understand the technical meaning of the term 'feed-forward', when and where it can be used and where it cannot be used? I have seen this term in various different areas. For example: ...
How can feedforward be used with PID for motion control
In a motion control system where a motor accelerates, coasts, and decelerates (setpoint is position, not velocity!), what would be the benefit of using feedforward with PID, instead of solely PID? ...
What is the relationship between feedforward control and bandwidth?
This is a control theory question, but because there is no control theory stack exchange, I thought this was the closest appropriate location: I've been studying feedforward control system designs, ...
Implementing Feedfoward from a Feedback Control System
In a standard feedback control system, you have a set point, a controller, a plant, and a sensor to enable feedback. The sensor measures the process variable (or in other words, the argument you are ...
Could you explain how feedforward is used in walking?
I am reading about feedforward in control system. And in this lecture, slide 49, the author says that feedforward is common in human systems. Example, walking, playing basketball, driving a car. ...
