2) A frequency equation and a buckling equation of Timoshenko cantilever beams subjected to both a subtangentially follow force and internal and external damping forces are then derived in the closed form to determine the damped flutter load and divergence load, respectively.
The damping coefficient is selected so that the vibrational energy it dissipates is equivalent to the energy dissipated in all the damping mechanisms, combined, present in the actual structure.
u,] are respectively the deviations in active power and voltage damping controllers' input signals, which can be achieved from (2).
