It is difficult to answer.
The kind of systems described are not seen anywhere else as far as I’m aware. But most other aircraft would have a pilot to take over when **** hits the fan. I think if this kind if controller is a prerequisite for AWE, we are probably in trouble. If not, it may be a worthwhile addition later.
To be precise: I’m talking about systems that can eg. detect a broken rudder and the. compensate for that by using the ailerons.
Such systems are difficult because the kite is difficult to control in the first place. Losing an actuator leaves you with a crap shot at saving the kite or not damaging something. If you want to be completely sure things work after a failure, my guess is you need lots of redundancy, and in that case there might not be as big requirements to the software anymore (function is more or less the same after a failure).
At this point in time I think it is more important to arrive at the simplest possible control structure, rather than going sofisticated. This will increase the odds of a: arriving at any solution and b: that solution being fairly robust.
Using no computer control is a tempting option (as it seems a few of you prefer), but I am not convinced AWE is easy to implement without software. Perhaps its easiest to start with software and a bit too much controllability, then try to shave it down to something simpler.
