Tony L. Schmitz,K. Scott Smithship of the editors, took place at the Mathematisches Forschungsinstitut Oberwolfach from May 18 to May 24, 1986. The great variety of topics covered by the contributions strongly indicates that also in the future it will be impossible to develop a unifying control theory of partial differential equ

Introduction,ation of the system from its equilibrium position. All bodies that possess mass and have finite stiffness are capable of vibrations. While some vibrations are desirable, such as the “silent ring” mode for cell phones, it is often the engineer’s objective to reduce or eliminate vibrations.

Single Degree of Freedom Free Vibration, concentrated at a single coordinate (degree of freedom) and it is supported by a massless spring and damper. Recall from Sect. . that free vibration means that the mass is disturbed from its equilibrium position and vibration occurs at the natural frequency, but a long-term external force is not pr
