1. An apparatus comprising:
- an active suspension including an electromagnetic actuator coupled to a plant in a vehicle;
a force bias eliminator coupled to the plant for causing the actuator to experience a zero-mean load;
a vibration isolation block for generating a control signal based on the response of a nominal plant to measured disturbances of the actively suspended plant, anda compensation system for modifying 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.

Abstract
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.
