Precisely. Looks like a classic control oscillation, possibly due to lag in the system. There are only a zillion ways to handle this sort of thing as it's an enormously common case. In fact it's within the realm of possibility that the "fix" for the next landing is just a tweak of some PID coefficients.
- baq 12y agoi'd guess the lag was accounted for, but due to something bad happening with the valve, it was different than expected. i don't do control theory but i'd assume there's a way of detecting this situation. maybe the valve needs an extra sensor or something?
