I'm pretty sure, that Doctor Doom is smart enough to try to find a way to get past Sentry's advantages, yet he was nearly always in disadvantage.
Even in a What If, written by Stan Lee Void killed Doctor Doom, including with everyone else.
While a What If does not matter much I still mentioned it, because it was Stan Lee who wrote it, who came up with the Doom character.
Doctor Doom is paranoid. He thinks that everyone is there to bust him up, so Doctor Doom is always prepared, when he leaves his castle. Hell, because of his tech and abilities he can go toe on toe with Silver Surfer and win more often then lose, yet he always had massive problems with Sentry.
I don't think Doom can actually defend him self against someone like the Void, who would basically use his powerful, raw molecule manipulation and simply attack him past the shields. I'm not even sure if Doom's shields would help him much at all, since Voidsentry already destroyed Kree-tech and the Kree have some sick gadgets.
I'm not sure if Doctor Doom would be able to find a way to steal Sentry's powers. Tech already managed to drain Sentry and revert him back to Robert Reynolds, but actually stealing it? I'm not sure.
I don't even know what to think about the weird energy drain by tech. To me personally it looked more like PIS, judging by other instances, where he was dishing out enough energy and stayed just fine for the longest time.
But if it's valid and not a plot device (and it was a plot device, to depower him and leave him useless once again on the battlefield), then yeah, Doctor Doom could come up with something like that, drain him and maybe kill Robert Reynolds, who would probably need more than 10 seconds to return.
The other way to defeat him, would to attack the Void with as much damage as possible and that amount of damage would have to be freakin' ridiculous. If he would manage to wear the Void down, so that he reverts to Robert Reynolds and if Doctor Doom would also maybe sacrifice a town or something in the process, Robert would maybe ask if he did it and then we would have the same outcome from Siege.
