The subject of the paper is vibration control of a cantilever beam with magnetorheological (MR) fluid. Based on the results of identification and energy analysis, a control algorithm for free vibrations damping of the beam was proposed. The algorithm was realized by controlling the current supplying the electromagnet. The free vibrations of beam were investigated for constant current and current varied according to the assumed control algorithm.
