So the control algorithm for the glide vehicle is going to correct for damaged ablative/control surfaces? I don’t believe this technology currently exists.
The scenario under discussion was the use of ablative surfaces to prevent damage. I'm not sure (I doubt) this is actually an effective countermeasure though.
Compensating for damaged control surfaces isn't impossible in all cases though, for the most part, fly-by-wire systems are servomechanisms which will scale their responses until the desired feedback is produced.
