Damping is an influence within or upon an oscillatory system that has the effect of reducing or preventing its oscillation. In physical systems, damping is produced by processes that dissipate the energy stored in the oscillation. Examples include viscous drag (a liquid's viscosity can hinder an oscillatory system, causing … See more Depending on the amount of damping present, a system exhibits different oscillatory behaviors and speeds. • Where the spring–mass system is completely lossless, the mass would oscillate … See more The damping ratio is a parameter, usually denoted by ζ (Greek letter zeta), that characterizes the frequency response of a second-order ordinary differential equation. It is particularly … See more The Q factor, damping ratio ζ, and exponential decay rate α are related such that $${\displaystyle \zeta ={\frac {1}{2Q}}={\alpha \over \omega _{n}}.}$$ When a second-order system has See more Viscous Drag When an object is falling through the air, the only force opposing its freefall is air resistance. An … See more A damped sine wave or damped sinusoid is a sinusoidal function whose amplitude approaches zero as time increases. It corresponds to the … See more Using the natural frequency of a harmonic oscillator $${\textstyle \omega _{n}={\sqrt {{k}/{m}}}}$$ and the definition of the damping ratio above, we can rewrite this as: See more In control theory, overshoot refers to an output exceeding its final, steady-state value.
