Abstract
A component vibration control system is disclosed. The vibration control system includes a first physical end stop, a second physical end stop, a damper assembly, a position sensor configured to determine a component position, and a processor in communication with the position sensor and the damper assembly. The processor is configured to set a first virtual end stop position, regulate a damping force of the damper assembly as the component moves toward the first virtual end stop position, and determine a second virtual end stop position based on a first distance of the component from a set position.

A component vibration control system, comprising:
- a first physical end stop;
- a second physical end stop;
- a damper assembly;
- a position sensor configured to determine a component position;
- and
- a processor in communication with the position sensor and the damper assembly, the processor configured to:
- set a first virtual end stop position;
- regulate damping of the damper assembly as the component moves toward the first virtual end stop position;
- and
- determine a second virtual end stop position as a function of a first distance of the component position from a set position.
A vibration control method, comprising:
- setting a first virtual end stop position;
- regulating damping as a component moves toward the first virtual end stop position;
- and
- determining a second virtual end stop position as a function of a first distance of a component position from a set position.
A machine, comprising:
- a component;
- and
- a vibration control system, including:
- a first physical end stop;
- a second physical end stop;
- a damper assembly;
- a position sensor configured to determine a component position;
- and
- a processor in communication with the position sensor and the damper assembly, the processor configured to:
- set a first virtual end stop position;
- regulate damping of the damper assembly as the component moves toward the first virtual end stop position;
- and
- determine a second virtual end stop position as a function of a first distance of the component position from a set position.
