You're right, it wasn't the software as such (more like the design of the system).
I just read more about PIO and it's funny, it reminds me of a short story I read a long long time ago, written by Arthur C Clarke, I remember the scene in it where a pilot is remote controlling his big space ship or plane of some kind, while standing on the ground. But because the remote is going through a satellite, there is a feed back delay, say 1 second or so. So when he tries to compensate for a wrong turn, a flavor of PIO is induced and the ship crashes.
Think that particular story was written in the 40's, good foresight of Mr. Clarke.
- HeyLaughingBoy 12y agoI like Clarke also, but this is less an instance of good foresight on his part than it is an understanding of feedback control theory. Control systems analysis advanced quite a bit in WW2 and by the time that story was written, the issues caused by low control bandwidth were probably well known.
