Abstract
In an active suspension system for actively suspending a plant, a fail-safe system controlled by a failure-detector has a selectively-activated damper coupled to the plant. The damper may be a separate element from the actuator. Under normal circumstances, the damper is deactivated and therefore generates no damping force. However, if the failure detector detects an abnormal state in the system, it activates the damper, thereby causing a damping force that resists motion of the plant.
