چکیده
A method for electromagnetic shunt damping (EMSD) will be presented in this paper. Compared to piezoelectric shunt damping, the proposed EMSD vibration controller has a number of bene ts. It requires small shunt voltages, can provide large stroke and can dampen larger mechanical structures. A passive control strategy is validated through experimentation on a simple electromagnetic mass-spring-damper system. Theoretical results are also presented.
