Mostly it's a matter of genetics. The nice thing about this is that you deal better with weather changes and don't get sun stuck as much as people who don't sweat so much.
A couple of things you can do - one is have a small surgery to remove your sweat glands. Or there are some medications you can take, or use Aluminum based deodorant (not very healthy, but seem to work well for some people who sweat a lot).

Another option is not worry about the sweat, but change things in your lifestyle to make your sweat not smelly, which is - if you smoke, stop smoking, if you drink alcohol, stop drinking. Avoid some type of food like curry powder, asparagus, some chillies, too much meat and so on, also, though you sweat exercise daily, especially type of sports that will make you sweat - like bikram yoga or spinning. And (and I know this sounds weird, but give it a shot) stop using soap and shower using water alone, don't use perfume or any products with scents (like deodorant, lotions and so on).
This is what my husband does and his sweat doesn't have any smell at all.
