  • What are the main causes of overshoot and undershoot of a signal?
    In this respect, the terms "overshoot" and "undershoot" are used to describe the step response of such a device (a) Overshoot: If a system of (at least) second order has two complex poles (a pole pair) the step response will exhibit overshoot It is possible to find a relation between the pole quality factor Qp and the amount of overshoot (in %)
  • control system - Exact definition of overshoot - Electrical Engineering . . .
    Now I have a doubt regarding the definition of overshoot The book — Modern Control Engineering by Ogata defines maximum overshoot as: The maximum overshoot is the maximum peak value of the response curve measured from unity If the final steady-state value of the response differs from unity, then it is common to use the maximum percent
  • control system - Intuitive understanding of relation between phase . . .
    On the opposite, if you want a nervous system with a fast transient response but can tolerate a reasonable overshoot, then a reduced phase margin like 50-60° makes more sense Finally, the very minimum value below which the response becomes unacceptably ringing is 30° and it is the value given by the modulus margin condition together with a 6
  • What can reduce overshoot and ringing on a simple square wave pulse . . .
    Per other answers and comments, I focused on bringing the overshoot down with some of the suggestions provided I did the following: shortened the leads going to and from the breadboard, adjusted compensation on the probes (one was slightly under compensated) This reduced measured overshoot from ~2 4V to 1 8V (over 5V)
  • pcb design - Positive and negative overshoot mitigation - Electrical . . .
    I read about overshoot and undershoot definition and causes, basically unmatched impedance and reflections, and some practical suggestions to mitigate this using a series resistance R (33 ohm to 120 ohm) or using a RC filter will also help in arresting the overshoot and undershoot Actual Waveform
  • measurement - TTL signal: output impedance, overshoot and other . . .
    In fact, the displayed sync wave (connecting the sync output directly to one of the channels of the scope, reading voltage over an open circuit basically) is an approx 4V square wave with a 400mV overshoot (approximately 100us long), and with an approx 200mV DC offset, which is consistent with my findings (TTL low levels are 0-0,4V, while TTL
  • switches - Unexpected Overshoot with Switch Bounce - Electrical . . .
    The overshoot amplitude should reduce dramatically, and The frequency of the oscillation should increase - which makes it easier to "damp out" (Hopefully this "damping out" is achieved naturally with just the existing components and wiring used in the real-world circuit, without having to add any extra components )
  • Output capacitor value calculation based on transient response in a . . .
    \$\begingroup\$ I understood now let me think more about it I am seeing Transient response curves in most of the buck datasheets but i can't able to find the difference in Overshoot and undershoot shown in datasheets do you have any document with actual curves measured Iout and Vout under transients \$\endgroup\$ –
  • current - Reducing Undershoot and Overshoot in a custom voltage . . .
    Start with 100 pF for the cap and 10 kΩ in series with the feedback to see what happens Adjust the feedback series resistor to get the step response you want Lower values will make a faster step response but will cause overshoot Higher values will decrease and then eliminate overshoot but at the expense of response time
  • motor - FOC Iq peak current overshoot - Electrical Engineering Stack . . .
    I have a FOC controller for a servo motor, where the Iq current can overshoot the maximum allowed Iq current (That is the reference value limit for Iq) by around 80-100% under heavy dynamic load When I use the servo motor with a constant attached load and give position or velocity commands, the Iq current does never overshoot more than around
