Claim:
1. An active suspension system for a sprung mass that is supported and movable relative to an unsprung mass, the active suspension system comprising: a suspension that comprises an electromagnetic actuator that is capable of producing an arbitrary force on the sprung mass that is independent of the position, velocity and acceleration of the sprung mass; a control system that provides control signals that cause the suspension to exert force on the sprung mass, to control the position of the sprung mass relative to the unsprung mass, wherein the control system implements a control algorithm with one or more constants; and a user interface that is operable to cause a change of one or more of the control algorithm constants that allows the user to tradeoff between an amount of relative motion between the sprung mass and the unsprung mass provided by the active suspension system, and an amount of vibration isolation of the sprung mass provided by the active suspension system, wherein the suspension system further comprises a first sensor that senses a position of the sprung mass relative to the unsprung mass and provides a position signal to the control system, wherein the control system comprises a position loop that is involved in controlling the position of the sprung mass relative to the unsprung mass, wherein the control algorithm comprises proportional and derivative constants in the position loop, wherein the user interface is operable to change the proportional and derivative constants in the position loop.
