摘要
In this paper the stability and control of complex dynamic system with elastic structure are investigated. As the dynamic model of the system is described by the coupled system of ordinary differential equations and partial differential equations, due to the effect of structure damping on the motion it is difficult to analyse the dynamic behavior of the system by the classical methods. By means of the spectrum and semigroup theories of operators in functional spaces, we have proved the existence and the uniqueness of the solution of the system. Choosing some control laws, the elastic vibrations, including the bending vibration and the torsional vibration, can be exponentially stable and the attitude orientation of the beam will be held.
