Abstract :
This paper presents a model for a series magneto-rheological (MR) fluid damper actuator (SMRDA). In this model the higher order dynamics caused by the MR fluid damper is considered. The effect of the MR fluid dynamics on the system properties, in terms of system bandwidth and output impedance, for the recently proposed series damper actuator (SDA) is analyzed and simulated. It is then compared with the series Newtonian viscous damper actuator (SNVDA).
