Has anyone tried to “peg” a cryptocurrency to USD? That seems like an ideal thing to have... Somehow change reward size based on exchange rate. That is increase supply when above 1:1 and decrease when below.

MakerDAO just launched its stablecoin, DAI. It maintains stability by a complex system of smart contracts and CDPs. The problem is much more difficult than simply increasing/decreasing supply.

Looks interesting! The trusted oracle part seems concerning as a single point of failure but I suppose it’s necessary.

There's also BaseCoin, another attempt at a "stable coin" with prominent investors:

Yes, there is Tether - which is pegged to USD - and somewhat controversial for reasons I don't fully understand.

The controversy is that it is unclear whether every Tether is backed by real USD. See: Tether's TOS, Bitfinex's banking issues, etc.
