“…They proved that the dissipation produced by damping δv t acting in the transverse displacement of the beam is strong enough to stabilize exponentially the system (7) for whatever the physical parameters of the model and reproduced a numerical counterpart in a totally discrete domain, which preserve the important decay property of the numerical energy. In the same way, in [17] Ramos, A.J.A., Freitas, M.M., Almeida, D.S. et al proved the system's exponential stability independent of any relation between the coefficients using terms of feedback at the boundary and consequently proved their equivalence with the exact observability at the boundary.…”

“…In [34], Ramos et al studied a one-dimensional system of piezoelectric beams with magnetic effects, showed by ρv tt − αv xx + γβp xx = 0, (x, t) ∈ (0, L) × (0, T ), µp tt − βp xx + γβv xx = 0, (x, t) ∈ (0, L) × (0, T ), (1.3) with boundary conditions v(0, t) = αv x (L, t) − γβp x (L, t) + ξ 1 h v t (L, t) = 0, t ∈ (0, T ), p(0, t) = βp x (L, t) − γβv x (L, t) + ξ 2 h p t (L, t) = 0, t ∈ (0, T ), (1.4) where ξ i , i = 1, 2 are positive constant feedback gains. The authors first divided the original system into a conservative system and an auxiliary system.…”
