Passive and semi-active vibration control strategies are investigated by experiments conducted on a SDOF system with magnetorheological damper. The frequency response functions and r.m.s. output to filtered white noise input, obtained in the passive case, are compared with those determined by using semi-active control strategies such as “balance logic” and “sky-hook”. It is shown that by appropriate settings of the control current supplied to the magnetorheological damper, the system vibration level can be appreciably lower than that of the passive system.
