An apparatus has an active suspension including an electromagnetic actuator coupled to a plant in a vehicle. A force bias eliminator is coupled to the plant for causing the actuator to experience a zero-mean load, and a vibration isolation block generates a control signal based on the response of a nominal plant to measured disturbances of the actively suspended plant. A compensation system modifies the control signal in response to a difference between the response of the nominal plant to the control signal and a measured response of the actively-suspended plant to the control signal.

Active suspending

A method for actively suspending a real plant in a vehicle includes modifying a control signal on the basis of a difference between a property of the real plant, as indicated by the response of the real plant to the control signal, and a property of a nominal plant.
