Damping in a multitude of engineering applications has a variable threshold requirement based on system excitation. Since system excitation is also variable; dampers are designed such that a maximum amount of damping is provided (based on the worst case for a structure), opposed to an optimal amount as a function of excitation. By implementing a hybrid damper design based on a bias component provided through a hydraulic medium and a variable component provided by electromagnetics; an optimal damping quantity can be obtained for a given excitation.
