An h-bomb fuses hydrogen by setting off a fission bomb surrounding it. Not much chance of controlling that.
A fusion reactor will fuse hydrogen by sqeezing it into a ridiculously dense, hot ball. If anything went wrong the magnetic field squeezing the ball would weaken and the ball would expand and not support fusion anymore.
There's never enough hydrogen in the middle to explode. Only enough to burn for the few milliseconds till they feed it more.

This is a very good question.
In order to make a fusion bomb you have to compress D-T fuel and heat to very high temperatures. Remember that when you heat gases they want to expand. The same is true for plasmas. So if you have a fusion reactor and you lose control. The plasma will expand which lowers the temperature of the plasma which slows the fusion reaction.

an h-bomb makes controled fusion. when it runs out of fusable material, it stops.
