【Abstract】 Using the method of basis perturbation, we show that the generalized eigenfunctions of a flexible Euler-Bernoulli beam system with boundary feedback consisting of velocity and angular velocity form a Riesz basis for the state space H, and give the computational fomula of optimal exponential decay rate of the system.更多还原
