Active suspending

An apparatus has an active suspension (12,14) including an electromagnetic actuator (28,30) coupled to a plant (16) in a vehicle. A force bias eliminator (60) is coupled to the plant (16) for causing the actuator to experience a zero-mean load, and a vibration isolation block (52) generates a contro...

Zusammenfassung:	An apparatus has an active suspension (12,14) including an electromagnetic actuator (28,30) coupled to a plant (16) in a vehicle. A force bias eliminator (60) is coupled to the plant (16) for causing the actuator to experience a zero-mean load, and a vibration isolation block (52) generates a control signal based on the response of a nominal plant to measured disturbances of the actively suspended plant. A compensation system (48) 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.
