How to find the values of parameter \$a\$ such that some conditions hold?
How to find the values of parameter \$a\$ such that the system will have a pair of complex poles corresponding to a dampening factor of \$\zeta=\frac{1}{\sqrt{2}}\$?
I've done Root Locus analysis of ...

How to create a frequency-dependent device with low losses at 50/60 Hz and high losses at 100 kHz
I'm working on a device to dampen high-frequency transients. Here are the specifications:
Rated current: 30 A RMS
Losses at low frequency (50/60 Hz): <10 W (required steady-state condition)
Losses ...

How can I explain contradictory damping performance between linear and nonlinear systems?
I have a 3rd order nonlinear dynamical system, representing a power system. After linearizing the system, it turns out that by increasing the parameter L_g, damping is reduced and thus the overshoot ...

Negative damping ratio for second order transfer function
For this circuit:
We get this transfer function (this is the solution of another student, but I did it by hand and I get the same thing):
Where the first damping ratio is negative. I read on another ...

Butterworth filter damping
A Butterworth filter has a damping ratio of 0.707 and is critically damped, but in general a damping ratio of 1 is critically damped, what is the theory behind this?

Optimum design of damping LC filter with parallel (R+C). There is a frequency in which value of R dosn't impact
Apologies for the not so clear title, but I don't know if there is a common phrase that describes the point of concern.
I am taking an online course about input filter design interfacing the grid and ...

How are break-away point and break-in points related to damping factor 'd' of a system?
I have to determine gain of P-Controller when damping factor = 1. So in the solutions it is mentioned that damping factor and break-away point are related. Please can anyone clarify how damping factor ...

How to find natural frequency from graph/plot of MATLAB Simulink?
I have compared my transfer function with standard characteristic equation of a 2nd order system and I found out that my natural frequency is 3 radians and damping ratio (zeta) is 0.5 but how can I ...

Confusions regarding Laplace transform
We know that Laplace transform has two parts, \$\sigma \$ and \$ j\omega\$.
\$\sigma\$ is the real part
while \$ j\omega\$ is the imaginary part.
Is it okay to say that the term \$\sigma \$ is a ...

Does a resonant peak produce a distorted wave form?
Context
I am re-enforcing my understanding of the frequency response. From 1, I understand that,
In an audio system, [the frequency response] may be used to minimize audible distortion by designing ...

Step response of critically damped PID controlled system
I thought that by definition: critically damped 2nd order system (ζ=1) does not have overshoot.
Is the above assumption wrong?
It might be on the verge of oscillation, but, it shouldn't oscillate.

Intuitive understanding of relation between phase margin and peak overshoot and/or damping factor [closed]
Second, percent overshoot is reduced by increasing the phase margin, and the speed of the response is increased by increasing the bandwidth.

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 ...

Damping Ratio Implications for an Increasing Resistance In an RLC Circuit
I have managed to derive the 2nd order ODE for a simple RLC circuit (this circuit is part of a booster dc-dc converter). I derived an expression for the damping ratio of the circuit and fact checked ...

How decreasing the effective load impedance in the secondary of a transformer heavily dampens it?
I am reading the operation of the ratio detector for FM demodulation. It works on the principle of diode variable damping (please see the figure here). The capacitor C9 restricts the changes in the ...
