Can flight control computers detect and help to avoid pilot-induced oscillations? With flight control technology available today like fly-by-wire, digitally augmented command inputs etc., I wonder whether any technical solution exists (or could possibly exist) to detect and counter the occurrence and dangers of pilot-induced oscillations (PIO). 

Consider for example a low visibility final approach scenario: 


Is it possible to detect an early onset of PIO and either augment pilot input to prevent further amplification of oscillations, or, less intrusive, give some (e.g. aural) warning to the pilot?
Also, a fully developed PIO situation might be detected and a warning triggered to increase awareness or prompt the pilots towards an eventual go around, similar to windshear warnings.


If feasible, do such technical mechanisms exist, or would they even be considered helpful by pilots at all? I imagine a critical part to solve would be not to override an actually intended control input by the pilot (that is within the usual safe envelope).
PIOs occur because the pilot senses a rapid movement and feels the urge to counter it. Key is the frequency of a few Hertz, so the pilot's reaction kicks in with a phase shift such that it promotes the movement, and low damping such that the oscillation amplitude grows over time. With a working FCS this kind of rapid movement should not happen.

However, once the FCS is not tuned to the situation, it can actually aggravate the situation and promote PIOs. The best known case is probably the 1992 crash landing of Tom Morgenfeld with the YF-22 prototype.


                
            

Here the gains in the FCS were set too high with afterburner on and gear up at slow speed.

Another case happened in the early phases of flight testing the V-22 Osprey. Here two of the three gyros in the control system were incorrectly wired and the pilot made a wrong control input.


                
            

So it is less the ability of the FCS to detect PIOs than its improved damping which never lets a rapid oscillation happen in the first place.
