Control design for an MR damper in a driver's seat

Abstract

The paper is concerned with identification and control of the magnetorheological (MR) damper recommended for suspended seat applications. It is assumed that the damper force is given by formula proposed by Spencer and the model exhibits the functional dependence of the parameters on the input current. The identified model is applied in control design for an MR damper in a driver’s seat. It is shown that the performance of the feedback system is improved while compared to the open-loop system.
