Claim:
1. An anti-backlash gear control device, comprising: a first bias module operable to generate a first bias to be applied to a first motor operable with a first gear; a second bias module operable to generate a second bias, opposite the first bias, to be applied to a second motor operable with a second gear, wherein the first gear and the second gear are operably connected to a load gear, such that rotation of at least one of the first gear and the second gear causes the load gear to move; and a command module operable to receive a drive command and output first and second command signals, wherein the command module outputs at least one of first and second command signals based on the drive command that are summed, by a summer, with the first and second biases, respectively, to generate first and second drive signals to operate the first and second motors to drive the first and second gears, respectively, and wherein the first drive signal equals the first bias, or the second drive signal equals the second bias to bias the first gear or the second gear, respectively, in contact with the load gear during operation.
