This paper considers the vibration control of a single degree of freedom mass-spring-damper system when subjected to an arbitrary, unmeasurable disturbance. The idea of a disturbance observer is introduced and it is shown how an estimate of the excitation can be derived and used to generate a control, which reduces the vibration. This control is shown to be robust with respect to the parameters describing the behavior of the system. Experimental results are presented which show the efficacy of the method when the system is excited by periodic, random, and impact forces. Comments are made on the application of the method.

Liquid Column Damper

For a direct unobstructed view over the ship bow, elevation of the bridge on top of deckhouse is required. With this deckhouse mounted over the engine room cavity, adequate structural stiffness is difficult to incorporate. The present study is intended to carry out a vibration control analysis using tuned liquid column damper (TLCD) which can be used against fore and aft vibration of superstructure. First stage analysis is done for the validation of proposed design of TLCD followed by comparative harmonic analysis of superstructure with and without TLCD, using finite element method.
