Multiple Choice

In the INS wobble discussion, which description correctly defines damped operation?

Damping in an INS wobble scenario comes from using velocity feedback to suppress the oscillation. When a velocity input is provided, the system generates a damping force or torque that opposes the wobbling motion, reducing its amplitude until the wobble is corrected. That’s why the description that matches damped operation is: Dampened — velocity input provided, wobble is corrected. If there’s no velocity input, the wobble would persist (undamped), and if wobble isn’t corrected despite the input, that wouldn’t be damped behavior.
