That's great news. I just happened to be working on an inverted pendulum
last week, when I came across both your and Steve's LegWays. I was using
NQC, so obviously it lacked precision, but it balanced nearly perfectly, but
I couldn't get it to stop running away. I used the "cart and pole" method,
though.
I tried tinkering around with predicting the velocity of the pendulum, but I
never got around to implementing a solution incorporating that. I'm working
on a website right now, hopefully I'll have it up in a couple of days, with
pics in a week or two (no digital cam).
