What is an overdamped response?
An overdamped response is the response that does not oscillate about the steady-state value but takes longer to reach steady-state than the critically damped case. Here damping ratio is greater than one.
What is a Overdamped system?
over damping: the condition in which damping of an oscillator causes it to return to equilibrium without oscillating; oscillator moves more slowly toward equilibrium than in the critically damped system.
What is overdamped oscillation?
Over Damped: “The condition in which damping of an oscillator causes it to return to equilibrium without oscillating; oscillator moves more slowly toward equilibrium than in the critically damped system. “
How can you tell whether an RLC circuit is overdamped or underdamped?
A circuit with a value of resistor that causes it to be just on the edge of ringing is called critically damped. Either side of critically damped are described as underdamped (ringing happens) and overdamped (ringing is suppressed).
How do you choose damping ratio?
A. The selection of the damping ratio for such a general application requires a tradeoff between maximum percent overshoot and the time where the peak overshoot occurs, tp. A smaller damping ratio decreases tp (which is desirable), but it increases the maximum percent overshoot (which is undesirable).
What is Underdamped vibration?
Explanation: If the system is underdamped it will swing back and forth with decreasing size of the swing until it comes to a stop. This is the equation of aperiodic motion i.e. the system cannot vibrate due to over-damping. The magnitude of the resultant displacement approaches zero with time.
What is Overdamped in RLC circuit?
The circuit is said to be overdamped because two superimposed exponentials are both driving the the current to zero. A circuit will be overdamped if the resistance is high relative to the resonant frequency.
What happens if the damping coefficient of a damped oscillator is overdamped?
Overdamping of a damped oscillatorwill cause it to approach zero amplitude more slowly than for the case of critical damping. The damping coefficientis greater than the undamped resonant frequency.
What is the characteristic equation of an over damped system?
is known as the characteristic polynomial of the system and D (s) = 0 is known as the characteristic equation of the system. Where is known as the damped natural frequency of the system. Now If δ > 1, the two roots s1 and s2 are real and we have an over damped system.
What is the difference between critical damping and overdamping?
With more damping (overdamping), the approach to zero is slower. Critical damping occurs when the damping coefficientis equal to the undamped resonant frequencyof the oscillator.

What is the difference between (I) and (II) over-damped and under-damping?
(i) when which means there are two real roots and relates to the case when the circuit is said to be over-damped. (ii) when which means there are two complex roots (as root ( -1) is imaginary) and relates to the case when the circuit is said to be under-damped.
