Utilizing (19) and shaping it as a standard form of an underdamped
system allows extracting natural frequency and damping ratio.
The present work concerns the existence of traveling wave solutions for the following underdamped

harmonic oscillator using (a) Granwald-Letnikov and (b) Riemann-Liouville (b) approaches.
The mathematical formulation is applied in an underdamped
system with 2DOF (Two Degrees of Freedom) excited by the base.
The eight-rotor UAV is an underdamped
system with four inputs and six outputs, according to the distribution of the rotor.
The oscillatory motion occurs when 0 [less than or equal to] [zeta] < 1, which corresponds to the underdamped
The damping characteristic can be divided into three categories: overdamped ([zeta] > 1), underdamped
([zeta] < 1), and critically damped ([zeta] = 1).
 One solution may be for monitor manufacturers to develop software that could detect the presence of an over- or underdamped
system and possibly even correct for this error.
After a more optimal tuning was applied to the PI block, a classic underdamped
oscillator curve can be seen.
The vibrations of linear 1 DOF systems with ordinary damping can be classified as underdamped
, critically damped, and overdamped according to the magnitude of the damping coefficient.
The plot also highlights the importance of designing the bearings in such a manner that underdamped
and overdamped conditions can also be avoided through proper design.
