1. No more volatility than any other coin

For this to happen the coin would need to be backed by something stable, or have a significant amount of value stored in it with huge buy and sell walls so the price never moves... By much.

2. complete identification of whoever owns coins

I'm not entirely sure how this could be done directly on the blockchain. The cryptocurrency platform needs to be open and have disposable and interchangeable addresses to accept payments. In order to have complete identification, you would need a central database that issues addresses/private keys to individuals that register their identity with said entity, at least AFAIK...

3. limited available currency per year

Not entirely sure what you mean by this one. Limited supply? Or limited inflation? Limited deflation? You could easily create a crypto currency that has a 1% - 2% inflation rate.

4. no mining, at least not the way it is done today

Then this would need to be proof of stake. Now this makes sense for a centralized crypto currency that is controlled by the central banks. Essentially every wallet would be a savings wallet with a percentage earned per year. However, this would mean the inflation rate would raise at the same rate as your earnings, therefore negating any earnings from proof of stake, as your currency is constantly being devalued.

5. centralized control (central bank)

See #2. They could have a private blockchain and only issue private keys to those that submit proper identity verification.

6. recognized in global economy

This coin would need to be backed by a world superpower for this to happen and the centralized coin be taken seriously.

7. used for national and international transactions

Each state actor would likely have their own coin at this point, as it gives them complete and utter control over their people. For international transactions, they could just use atomic swaps to exchange one currency for the other.
