In this paper, the problem of adding damping to a vibrating string is considered. Instead of using feedback control or frequency domain techniques, a wave-analysis approach proposed by von-Flotow for beams and trusses is used. This technique is based upon the premise that resonances are caused by waves reflecting off of discontinuities. By eliminating the reflections, the resonances will dissap...

A critical study of the process necessary to create structural control models is made. Exact closed-form solutions of beams and truss-beams continuous models open and closed loop dynamics are given, and used to evaluate the low frequency accuracy of hand prefined finite element models. For trusses condensed models and refined joint behavior are considered, using the equivalent continuum approac...
