Active control of bending vibrations of Timoshenko beams using state observers

St. Petersburg Polytechnical University Journal: Physics and Mathematics
When describing bending vibrations of elastic beams, the transition from the Bernoulli – Euler model to the Timoshenko model leads to a complication in the dynamic behavior of the beam and to the emergence of new dynamic effects and a new spectrum of ...
