There's an interesting crypto protocol called Reflexer[1] that uses a PID loop to alter interest rates and incentives to maintain the stability of a stablecoin/debt coupon called Rai.
This allows the asset to remain relatively stable[2] in response to actual market forces. At the time of posting there are over $35m worth of Rai in circulation[3].
