The control of flexible structures for those systems with actuators that are modeled by second order dynamics is examined. Two modeling approaches are investigated. First a stability and performance analysis is performed ...

The frequency response of nonproportionally (or nonclassically or non-Raleigh) damped linear lumped mass systems is discussed here. The exact method, via Laplace transforms, is presented and the practical difficulties ...

This paper forms a literature survey on lumped and distributed parameter, linear, viscously damped, dynamic systems, possessing non-classical modes.

The time domain response of non-proportionally damped or non-classical normal mode or non-Rayleigh linear lumped parameter systems, as otherwise called, is derived. Modal analysis is used to transform the governing equations ...

Although the response of undamped or at least proportionally damped linear systems can be determined easily by modal analysis, the prediction of the response of nonproportionally damped linear systems requires either more ...
