PROPORTIONAL FEEDBACK-CONTROL OF AN ELECTRORHEOLOGICAL VIBRATION DAMPER

In this paper, the authors derive a quasi-steady model of an electro-r heological damper under proportional feedback control. Using this mode l it is shown how? through the choice of two gain terms, the input/out put characteristic of the closed-loop system can be linearised, Also, through the choice of a third gain term, the slope of the force/veloci ty line can be determined. A numerical study compares the performance of open- and closed-loop schemes and indicates clearly the working ran ge over which linear behaviour can be obtained.
