Hm. I never thought that Frodo wanted to directly command others, or that he trained his will to dominate others. He only "uses" it to "command" Gollum - and that "using" was more like threatening: "If you touch me, I'll use the Ring and command you to jump to the Fire."
By the time Frodo got to the Cracks of Doom, he was totally broken by the Ring. He couldn't think of anything else. He saw it all the time as a wheel of fire, even when his eyes were open and looking at something else. I don't think that he ever intended to become a Dark Lord: like Maril said, Frodo's words on Mount Doom were not "I'll become Frodo the Great and cast down the Dark Lord and..." but "I do not choose to do this. The Ring is mine."
The Ring had eaten away a part of Frodo's soul, and it was almost in command of him. It was just impossible for him to throw it away - but he was still just a small hobbit and he didn't want to become a Dark Lord.
