The "Skyhook theory" is an idea that the object can maintain a stable posture if it is moving suspended by an imaginary straight line. The imaginary line (body velocity = 0) is calculated based on the value provided by each signal.
The advantage by the skyhook theory is follows.
- Optimum damping force: Only when a body is moving, the damping force is produced to keep the movement of the body.
- Minimum exciting force: Damping force does not act for a change in road surface and does not effect for the body through damper.
